Jeep Cherokee Start Stall Idle Problems

    Hello Tracy - is this the 2.8L V-6 or the 4-cylinder engine?

    Sounds like a bad clutch master or slave cylinder. When one goes... the other is usually a short breath behind. Don't waste time / $ on the aftermarket parts on this one as it's simply not worth it. You'll end up replacing them on a monthly basis so this one of the rare times I'd go to the dealership and pay the full, highway robbery rate. Dealership kit includes slave, master & hydraulic line.

    I'm not sure if your XJ has the internal or external slave cylinder. IF it is the internal slave cylinder (inside the clutch bell housing...) then I'd also bite the bullet & have the dealership install it. External slave - not too bad to do. If you can do a brake job & bleed the brakes then you can do the external slave swap no problem.

    Another possibility is a leaking rear main seal... does your XJ 'mark it's spot' with oil whenever you park it??? If so, open up the dust cover for the clutch bell housing & look for a dirty, oily film on the flywheel. Oil = slipping clutch.
  • 2001 GC. After driving for about 20 minutes and longer, when turned off it will not start. Seems to turn over, but like no feul is being delivered. Does a GC have a cam shaft position sensor?? but usually when one goes (cam shaft position sensor) it will never start, this starts evry time if you let it wait for 30 min.. It has me baffled, any suggestions?
    Thanks,

    Last summer, my jeep began having start problem. It would turn over but not start the engine on the first try. After stopping, it would start on the second try. It seemed that as the temperature soared to over a 100, the starts got worse. Probably not related....but it was a very hot summer and it was suggested that I switch gas, change my keys, use a fuel injection cleaner, fuel additive...and have it checked out. All of which I did. The auto shop found nothing wrong and could not duplicate my start problem.

    Fall arrived, the temps got cooler, but the problem still occurred. Then a new symptom started. While idling in traffic, the engine would "burp" slightly and the jeep would go dead. The engine light came on and stayed on until the car was recranked. This happened twice over a period of a few days, so I took it back to the shop. They checked it out again and found nothing wrong....but suggested a replacement of the crankshaft sensor. $250 later, I still have the same problem.

    The mechanic then suggested I turn the key on just to illuminate the dash. Cut it off and if it cranks on the second try, he says it needs a new fuel pump.

    Here are other repairs I've made this past year. New water pump. New battery. This is my second jeep and my older 2000 has 175,000 miles with none of these issues.
    Can you help?

  • Hey everyone, I have a 3.7L Laredo and have had idle problems for about a year. About a year ago it stalled on me twice while driving at fast speed. The first one was slowing down for a stop light going about 50mph and the second was getting off a highway, onto another. Both times, put it in neutral, started up and kept driving. There was some sort of update they did on my car and it hasn't stalled since (thank God!).

    The low idling is still a problem. After a 30 minute drive home, I will be at a complete stop, a stop light or whatever, and it will drop to 300-400 rpms and then catch itself and go back to 500-600 where it seems to feel and run fine. I've had the throttle positioning level "repositioned" and serviced. :mad:

    I've read that it could be a need of replacing the TPS or even the IAC motor. All is under warranty and dealership keeps saying nothing is wrong with it since the diagnostic aren't coming back abnormal. I've taken it in repeatedly for this only to no avail! I've thought about the lemon law but it's something that seems so simple to fix yet they don't see anything wrong with it.

    Any suggestions? Anyone else have this problem? Did you get it fixed?

    If you're reading all of that on this thread be aware that your engine and your vehicle is not the same as 9/10ths of the posting vehicles in this thread. Most are 4.0L inline 6's and a mix of Grand and standard (XJ) Cherokees.

    This site, unfortunately, doesn't move posts to new threads & people just tack on to the last thread that's close to what they're experiencing but different years, different engines often mean different solutions.

    I'd suggest posting the same info as a new thread but use 2006 3.7L GC Idle issues as the title.

  • My jeep has been acting up since the winter started. My battery doesn't want to hold a charge if I leave it sitting for a couple of days without starting it. I bought the battery the same time i bought the alternator which has been less than a year. Also when I jump it it doesn't hold an idle in that it starts and dies immediately. If I keep my foot on the gas it'll stay running but soon as I take it off it dies. Sometimes it will run without me having the gas pressed down but it will die if I come to a stop or the rpms will swing really low then pop back up to a little more than a thousand at idle. I thought it could be the throttle position sensor so I swapped that out it didn't fix the problem. I would love it if someone had some insight on this one.

    Thanks,

    Jay
  • Engine used to start in one crank revolution. Now it takes 7 or 8 revs. If I turn on the key to the on position (just before start) and let it sit 10 or 15 seconds, it starts pretty good. Any suggestions?
  • I have a 2005 Jeep grand cherokee 3.7 6cyl that used to be the best car ever but is becoming a headache now. The lights in the dash will dim on and off at dawn which I thought it was my imagination at first. Even the over head lights were doing it, but not headlights or anything. Because the dealership could not duplicate it, they could not fix it. Now it is sitting in my drive way and will not start. It clicks, but will not start. After an hour, I went back out and started it without any problems, tested the alternator by turning everything on full power and no lights would dim or rpms would not fall. Battery is clean, cleaned connectors and such. Did my best being a chick. Anywho, now it wont start again???? I went and tried and it is just clicking again almost like the starter is locked up....oh, and when it is having this tantrum, the service engine light,the oil light, and the service electrical break system warning indicator comes on. But when it starts, it is all fine. Any idea anyone????????????????????????????????????????
  • what year is your jeep? sounds like the same problems im having.....
  • tuggajbtuggajb Posts: 646
    this may sound funney but i would change the battery if has not been changed is 3 years old and could be going out i would do this before i tryed anything else jeeps like to have bat voltage just right
  • Sunshne,
    I have a 2006 that did that with all the gauges flashing at me. I too thought it was my mind playing games, but I took it to Jeep and they did some sort of update and replaced my computer. That fixed that. Just recently, as of Thursday, it didn't start up. It was freezing cold that morning so I figured that was it. We were leaving that morning for a trip too so I was like oh great! Drive went fine, parked at hotel, and next morning decided to try to start it up. Nothing. The boys looked at the battery and it was all corroded (sp?) even to the point of my cable to it almost being corroded in half! It's at the dealership right now being fixed, replacing the battery and the terminal. Hopefully it's the last of my problems otherwise I will trade it in!

    Has your Jeep ever had any idle problems when warmed up and driving for about 30 minutes?

    I hate how they have to duplicate something in order to fix it!!! I thought there was something in the car that recorded all the stuff that went on and such. Can't they look at that?
  • Hi, and thank you for replying. I have had issues with it idling. It will drop to like 5 rpms and sound like its going to die. If im at a light or stop sign, it scares me so i just push the gas a little to make sure its not going to die. The battery was tested and it is perfect, along with the alternator and it is not throwing any codes. Its really dissappointing. I really like my jeep too. They said because it is out of warranty and I have an extended warranty that they can not just "guess" the issue. So I am really dissappointed with that since I bought the most expensive extended warranty through chrysler/jeep. I just don't know what to do besides drive it until it breaks with me and my two toddlers and be stranded until they pick it up?? its rediculous!!!
  • Mine does the same thing. I've sat there and watched it do it. It's never actually died on me because it'll catch itself. Mine idles at about 600-800 rpms, and will drop to 300-400 rpms but catch itself and go back up.

    I am not going to buy an extended warranty through Jeep, I'll go elsewhere so I can take it to my mechanic.

    I've learned that if there aren't any codes that are flagging the computer then there is nothing they can do. They always need a damn code! What happened to process of elimination? It drives me crazy!!!

    I am in the process of contacting Chrysler LLC to file a complaint!
  • Update to my previous message. My jeep is having a new problem now. At speeds of around 50 to 60 mph, it will suddenly seem to die, but then catch up again. Very scary on the interstate. And the engine light comes on when this happens. It goes off by the next day. Any ideas anyone??

    I'm still starting it by turning the key to the second position, then off. After that it starts up but sometimes hesitates a few seconds.

    Thanks!

  • what does it do? mine will sit there and tick like the battery is dead, but it isn't. Sounds like its trying to fire but will not catch...I am taking mine and leaving it overnight at the jeep dealership mid next week to find out what is going on cause it does it every morning or on every cold start for me. So if i drive it there, it will not do it?? Figures...right. But after 6 or more times of trying to start it, it will start. I dont know what the deal is with jeep, but from all the reviews I have read, it will be my last!
  • The battery was replaced in Aug. last year. The battery has been tested and the alternator. I am starting to wonder if its my starter cause on every cold start, it ticks multiple times. I have to let go and try again 3 or more times before it slowly catches. I dont know anymore. This jeep is going to have to go!! I wish it would just completly break instead of leaving me in the guessing game!

    After starting my Cherokee and letting it idle for 3-5 minutes, I turn it off. Trying to restart, it will crank, and with the help of pumping the gas it will finally turn over. If I let the truck rest for 10-15 minutes, it will start just fine. I'm thinking that it might be an electrical issue. If anyone has had this problem before please contact me.
    Thanks for the help

  • my jeep will stall while going down the road. sometimes it will start itself back up and sometimes i have to stop and start it. the check engine light does not come on and ive changed the fuel filter, the fuel pump relay, and even taken my fuel rail and injectors out and soaked them in sea foam. ive had people say it was the crankshaft positioning sensor, the "brain", and maybe even my fuel pump. can anyone help?

    I have a 97 Grand Cherokee with the Quadratrac Transmission.

    When I am at slow speeds (under 10 mph) and turn left or right at 3/4 or more steering wheel deflection (like pulling in and out of a parking space) the front end of the truck seems to 'bog' down. You get the impression that the tires are rubbing against the wheel wells but they are not.

    Is this normal or do I have an issue?
  • hat2214hat2214 Posts: 2
    The engine revs slightly while "coasting". no other problems with idle in park, only when driving. any ideas?
  • lunghdlunghd Posts: 61
    What do you mean by revs? What RPM's? In gear? Out of gear (manual tranny)?

    If auto tranny : Does it have pulsing rev & release while coasting down a grade or slowing down without braking? If so; = torque converter locking & unlocking - nothing to worry about.
  • hat2214hat2214 Posts: 2
    yes, auto tranny and it is like a pulsing but it does not slow down noticably anyway. the rpm is between 1 and 2 and goes up and down between them when in gear while coasting. thanks for the help
  • Hey everyone. It's been a while since being on here. After my episode of the battery being all corroded while on vacation, I immediately took it to Jeep to have them check it out. Sure enough the battery and wiring harness that goes to everything (the battery, alternator, fuses, etc.) was bad. They replaced both and I HAVEN'T HAD ONE PROBLEM SINCE!!! :) I probably just jinxed myself by saying that but oh well.

    I sure hope this may solve some of the problems for y'all. Good luck!

    After all that I've gone through with this Jeep hasn't put much faith in me that they are good cars. Not sure if I'll be getting another one when this one dies.
  • hey had the same problem on a 99. it ended up being a ecu problem. changed ecu and it works fine now..

    My 2004 Jeep Grand Cherokee Laredo v6 has been in and out of the shop (dealer) for over a month with the same problem. Each time I bring it in they diagnose/fix something else and it comes back with the problem developing again. They are stumped - and I'm not sure what to do. The car has 85,000 miles. I don't have the "codes" I keep reading about here (I'm not a car techie), but here is the history, any help is appreciated.

    Symptoms: at around 65 mph (or 2000 rpm) I feel the car hesitate a little, and the rpm needle moves a bit weird. Over time (and multiple service visits) this started happening at lower and lower speeds (like 40 or 45, eventually). One time i was on the highway and it hesitated so much it stopped running (check engine light appeared), and I had it towed to the dealer (they paid the towing).

    Here are the things the dealer tested, diagnosed and replaced, over this time (in chronological order):
    1. Engine misfire - replace spark plugs and 02 sensor
    2. Fuel induction cleanup service - cleaned fuel rail, injectors, intake system & throttle body
    3. Found a short in the ignition coil - replaced coil, and fuel filter
    4. Replaced throttle position sensor
    5. Replaced PC module (main computer for engine)

    Here is some older regular service history too (in case it's helpful at all to know): Ignition tune-up, replaced brakes, add coolants, replace shocks, replace transmission fluid & filter, replace front pinion seal and flush brake fluids.

    Anyway the car is still hesitating at around 60 mph. Although it seems less severe and less frequent I'm scared to keep driving it and I don't know what to do. The dealer once even sent the car to an independent mechanic (he's the one who replaced the PC module) and hasn't been charging me any more for service.

    Help!?
