    I have a '99 a started having the exact same problems in the last month -- trans not disengaging at stops and coming out of gear and stalling on the highway, only to start back up again when I pump the gas. No idea what is going on. I'm going to contact my dealer and see if they know what it could be. If you figure it out before I do, I appreciate you sharing the diagnosis...I'll do the same.

    Hello. I'm having the same problem. Do you suggest changing the relay first. If so where is it located. :(
  • I've changed:

    Front/Rear Oxygen Sensors
    Checked Fuel pressure on the rail
    changed fuel filter
    changed water pump
    cleaned out throttle body
    checked idle control motor relay it's still in decent working order.

    I've heard someting about MAP sensors which have shaken loose of thier contacts and need to be soldered back.

    Could the Idle Control Motor be bad and stall the car out only sometimes, and only when coming to a stop, idling, or in park, and twice while driving and letting go of the accelerator.

    I've also heard the Vehicle-speed sensor could be the cause of the problem... guys I LOVE MY JEEP, and I've put a lot of money into it, but I never could have imagined it was going to bring me such heartache. Anyone who's fixed this problem please help me. Please let me know, I'm 19, a restaurant manager, Just getting used to adult life, and now this has been the month from H*ll. Please help guys, I need this car for work, everyday. I can't fail, and Miami public transportation has to be the worst in the WORLD.....

    PLEASEEEE my mechanic watched my car stalll out on him right in front of him, while in park, and he told me theres nothing wrong with the car, because there is no code on the computer......

    Well let me add to the 2005 LGC Tranny problems. I had the shuddering problem 3 days after I leased the truck, took it in for the TSB that stated to flush out the tranny to remove the moisture from inside. PIcked it up the next day, drove it home, had to take it back for the same problem once again. So I have less than 700 miles on it, and already I have gone in twice for the same issue. Completely unacceptable. Now the Service Manager told me they are going to drop the transmission and do a full overhaul on it to ensure all moisture is removed and to perform a thorough eval to make sure nothing else was damaged inside. I already called Chrysler Jeep and reported my issue so that there is a history. I am patiently waiting the outcome, the deal has been great though. They provided a FREE rental car which is the least they can do in my eyes.

    I have a 1997 JGC Laredo 4.0, optional 4x4, inline 6, automatic with 120,000 miles and I am having trouble with stalling also.

    This is what happens:
    1. Put key into ignition and turn to start...starts fine
    2. I check the dashboard monitor, no lights, and all gauges are normal (temp just under 210)
    3. Apply foot to brake and shift from Park to either Drive or Reverse.
    4. Car stalls

    Car will remain remain running in Park without problems, but IMMEDIATELY shuts off when I attempt to shift from Park to another gear. I live in Wisconsin and it is 88 degrees today and the vehicle was sitting in the sun. There is a slight coolant leak but the overflow still has coolant. I tried 4 or 5 times with the same result. I then waited 30 minutes and the car started and ran fine. Does anyone know what the problem may be? I called my mechanic and he told me it could just be very overheated from my errands but the temperature gauge was showing normal. Thanks much in advance.

    I took my GCL with the Hemi to the dealer with the TSB in hand and they told me that it does not apply to my transmission. They said it was for the 300C not Jeep. I am still having the same problems of the shuddering but it seems to be getting worse. I now have 1700 miles. This vehicle is the worst piece of junk I've ever driven.
  • I posted a couple times on my jeep stalling for no reason, it stalls in park, it stalls in neutral, it stalls at idle, it stalls while driving on the highway. And it's whenever it wants to. totally random.....i thought it was an idle problem, but twice it's stalled while driving...

    should I just take the bus?? and give up my jeep for good...I love it to death and I know there's a definite reason for it....something small and loose, some sensor not working correctly, a malfunctioning something or other, but I've spent $400 in the last week to not have it fixed......

    Miami busses suck....

    What's a Jeep lover to do?
  • jkramjkram Posts: 17
    I have posted about my Jeep Grand Cherokee with the Hemi bucking and stumbling many times. Has Chrysler Jeep fixed any of the others that posted the same problem? I've read many complaints, but never see anyone say they fixed it. If you have success please post so we can get ours fixed!!!! Anyone at all!!!!

    When I start our Jeep it rev's up really fast and idle's fast until we put it in gear. Does anyone know what might be causing this? Also, when we are traveling down the road with our cruise control on at 60 mph, the engine RPM will be at 1800 and then it will surge up to 2000 and then back down to 1800. It does this quite often. Does anyone know what would be causing this?

    A mechanic friend of mine once told me that all engine running problems can be reduced to this: An engine needs only fuel, air and spark, and for them to come together at the right time. I mention this because air is an often overlooked component. In the case of stalling at idle, check to make sure the PCV valve and supply tube are clean and clear. When the throttle body is closed (foot off gas pedal) the engine is more dependant on this air supply. This may not be your problem, but at least it is an easy check and cheap repair.

    Hi-We've had our 1999 Grand Cherokee Limited since last August and have had ongoing issues: Erratic idle, stalling when put into gear, hesitation at highway speeds when letting off the gas. :( Dealerships have changed plugs, cleaned the idol control whatever plus some other things I don't remember and no improvement. Of course, the warranty we bought covered none of the above.
    We're a bit upside down in the loan and thinking about getting rid of it, but would hang onto it if we were confident this could be fixed.
    Any suggestions? And does anyone have a reliable mechanic that won't rip us off in Rhode Island?

    What year and model is it? I have a 1994 Laredo. It does the same thing. It goes through phases where it will not stall for months and then all of a sudden it starts stalling randomly. A mechanic told me that there is a known bug with a sensor (cam shaft positions sensor I believe) whichs malfunctions and triggers an engine shutdown. But have yet to find an official report from Chrysler.

    My solution may or may not work for you, but worth consideration I think. Read below:

    I had a similar experience, spent all kinds of $$ at the dealer, only to almost get cut in two while leaving the dealer's lot when it stalled in the middle of two lanes of traffic after the expensive repairs (including complete tune up, wiring harness, fuel injector work...) because all that they did, DID NOT correct my problem. I brought it to a local small repair shop in my town and explained the situation. He asked that I leave it with him while I was at work that day and come back for it that night - he had an idea. My wallet was almost empty after what I had just paid for the other worthless repairs, so I was hesitant to leave it without having some idea of what he had in mind. He told me to trust him, if he was right in his thinking, it would not be an expensive fix. So, it swallowed hard and put my trust in him. When I returned later that afternoon I asked how things went and what I owed. He told me I didn't owe anything yet, drive it for a couple days and let him know if it was any better. I told him I would know when I Ieft his driveway if I was all set, as it would not idle well and would almost always stall while waiting to pull into traffic. I got in the car, started it up and headed for home. I couldn't believe it!!!! The car never hesitated, never shuttered, never ran smoothly from that point forward. What was the fix? He disconnected the EGR valve (where I live they do not check emissions on that year vehicle so he didn't go to the expense of replacing) and put a screw in to block air from entering the line. It ran great!!! I was so grateful and happy, and he only charged me $15.00!!!!!!! I still to this day can remember how great it felt to have the problem solved and my Jeep running reliably again. Not sure this is what your problem is, but it sounds similar. May be worth a try. Good luck.

    :cry: the hose you are refering is the over flow line for radiator coolant not the A/C drain
  • 98jgc98jgc Posts: 2
    I have a 98 JGC with the six and 95K. When I turn on the air you get a very strong mildew smell comming from the vents. Does any one know what the problems is and how can I fix it? Thanks
  • paulepaule Posts: 382
    Yep. I know.
    I posted an apology a while ago. I was going by a comment in my repair manual which showed the drain hose on a '99 (I own a '98) and mistook the coolant drain hose for the A\C drain hose.
    Grab a flash light and look inside your passenger side framerail. Better yet, get inside the Jeep and pull up the carpet and find it that way.
    I have never had that problem on my '98 so I don't really feel like taking my vehicle apart to find a problem that doesn't exist for me.

    I found a small amount (half of the size of my hand) liquid under my 04 JGC Ltd with 16K on it. This morning. I don't think it's A/C water because I didn't use it the day night before, but it felt like water when I touched it. I didn't taste it. Does anyone know what kind of liquid that could be? I did use A/C for a bit the DAY before, but this morning I went somewhere and parked my car, after about 3 hours I came back and the liquid was there. Any comments and help are appreciated! Thanks a lot!

    Hey. I'm new to this. And the world of Jeeps. I recently got a 98 Cherokee Classic Model. It has an inline 6 engine with 225 horsepower. However, it is only a two wheel drive. Recently when i turn the ac on and put it in gear I hear this loud screeching noise that has turned several heads from neighboring houses coming from what sounds like the belt. I have already replaced the belt. That cost 100 bucks. It didnt work. I've taken out some of the R134. The mechanics think too much pressure was being caused by that. However, that still didn't work. I tried several theories earlier. It only squeaks when the ac is on. No matter how low or high it is. It eventually winds out. And it starts when i come to a complete stop and start again or when i change gears. I don't want to spend tons of money on it only to find out that theres nothing that can be done. Has anyone else had this problem. All help and comments would be greatly appreciated. Thanks
