    I have a 1999 Wrangler and the first time I crank it each day it runs fine until I shut it off for a short period of time, when I crank it back up and take off it starts to spit and sputter for a while. If it sits all day while I'm at work it runs fine. I have replaced the wires,plugs,cap and rotor.

    It is likely the fuel lines are the problem. When they get very hot like they do in a engine compartment with a hot engine and little airflow, some of the fuel in the lines may vaporize causing the fuel injectors to push out fuel with pockets of vapor when you first start up. If this is the problem it should only last for a very short time and then the engine should return to normal as fresh cool fuel enters the lines. This problem may be caused by lower than normal fuel pressure. You can also try insulating the fuel lines at the top of the engine right before they go into the injectors, just don't use anything flammable.
  • I have a 1997 Jeep Wrangler and my spedometer lights at night do not turn on, as well as all my rear break/blinker lights are out as well. I was wondering what I need to do to fix the problem. Hope someone knows what to do.

    Thanks,
    Mike

    It does not have to get hot, example I can crank it first time after sitting all night and drive it for less than 5 minutes, shut it off then re-crank and when I take off it statrs to spit and sputter I even hear it pop some times.

  • Hey everybody, I recently got into a fight with a phone pole and am in need of a full driver side door. Anybody from New York know where I could get one without sacrificing my first born?

    I forgot to ask....is there a possibility that this could have been the cause of the water on the driver side floor?

    The auto parts section of your nearest craigslist would be the best starting point.

    my 1997 wrangler 2.5 was running great....then it decided to run at max speed only!
    While on the local hiway, it suddenly in traffic, accelerated to max RPM. I have checked throttle linkage, and all of the obvious, check for codes....nothing! The throttle body butterfly is closed, and the linkage, return spring, etc. appears normal. I suspect TPS, but shouldn't it set a code? Help, Please!!!
  • jphackjphack Posts: 2
    I just changed the TPS, no difference!! It still still goes to full throttle without touching the accelerator. :confuse:
  • I have a 99 wrangler and have a problem we just can't figure out... after driving for about 20 min, and the jeep heats up, it acts like it is running out of gas and won't idle unless you take your foot off the accelerater, it almost always does it when going up a hill. If you sit and let it cool for a for a few minutes it will run again for a 1/4 mile and starts all over again. We have replaced the fuel pump, ignition coil, pickup on the distributor. It also had new plugs, wires and dist. cap and rotor button prior to this problem. We also checked the cat. converter and it wasn't plugged. Any help would be Greatly appreciated. Thanks
  • Hey I just read one of your past posts about your jeep acting up after you drove for a about ten min. Mine is a 99 and is doing the exact same thing. After about 10 minutes it acts like it is running out of gas, shut it off and cool a few min then you can go another 20 feet and it does it again. We replaced the fuel pump, ignition coil, dist. pickup, and it already had new plugs and wires. Did you find out what the problem was? I'm so sick of throwing money away, would really apprecitate any info you have.
    Thanks,
    Kat
  • Hey folks need some help. I drove my wrangler all day stoppin here and there. At one point when I went to start it, as soon as it was turning over it made this nasty noise and sounded like someone threw rocks under the hood. Then it was smooth. I went to my next stop...same thing, I checked to see if anything was loose...nothing. When I got home. I started it again, it was fine!??! Plus at one point I was driving, and the "check gage" light came on and the oil gage was bouncing from the left to the middle of the gage. Back in forth and then it stopped and didnt do it again. Is my car haunted??? Am I carzy?? Please help...

    :confuse:

    Check your throttle position sensor. I had identical problems once I gave my Jeep a mud bath while offroading. :) Simple $50.00 fix and you can install it yourself easily with a torx bit and socket set.

  • I tried to engage the 4wd on my jeep and the lever seemed to jam. Eventually it went up but the 4wd light did not engage and the gears seemed to spin. I also had trouble getting back into normal drive but it eventually did.

    What steps would i take to diagnose and repair this problem?
  • burntupburntup Posts: 64
    A question or two...or five...or 7.
    When you attempted to engage Four Wheel Drive was your JEEP moving or stopped?
    Do you have an automatic or an manual transmission?
    How often do you engage Four Wheel Drive?
    When you attempted to disengage was your JEEP moving?
    When was the last time the front axle was serviced?
    ...last time the front drive train was submerged?
    ...miles on JEEP?
  • 1) stopped
    2)manual
    3) rarely, mostly highway driving here in Germany
    4) reengaged while stopped, but moved forward a bit thinking it was in 4WD but light was out
    5) unknown, not in the last 9 months since i purchased it
    6) last time it was submerged was 5 months ago
    7)80000 miles on jeep

    Thanks
  • I HAVE A 2001 4 CYL W/AC AUTO WRANGLER. THE ENGINE RUNS FINE FOR THE FIRST 4 OR 5 MILES THEN MISSES AT IDLE AND SLOW SPEEDS. MASHING THE GAS PEDAL TO THE FLOOR AND IT TAKES OFF ONLY TO MISS AGAIN AT SLOWER SPEEDS. ANY IDEAS

    hey yall i just bought a 2000 jeep wrangler tj and i freakin love it. it has a soft top and half doors and i was playin around with it gettin to know all the stuff and i noticed that when i take the doors off the interior light does not go off and i cannot find out how to turn it off, ive tried many things. now, i found the sensor on the door frame where when the doors pushes it in the light goes off, but how does that happen if theres no door at all?! anyways i know its a rookie question but im new to jeeps, so if i could get some feedback on my little dilema i would be more than greatful, because i love driving with the doors off. thanks in advance! :confuse:
  • Open up your glove box and take it out. It should just be on a strap and then easily removed. On the side of the box is a listing of your fuses. One of them is for your door sensors. I believe on my 04 it is number 7. Also I found that once you remove the fuse you still have to press the sensor to reset it and keep it from coming on again.
  • erickplerickpl Posts: 2,735
    Actually it is Fuse #4. not sure if you have to press the sensor again, but I don't on my 97. I installed a switch that I mounted to my OBDII port that let's me deactivate the circuit easily.

    Has anyone had to replace their front rotors before their brake pads (50% wear). My rotors are warped at 25000 miles. And imagine this chrysler will not stand behind this.
  • rebel99rebel99 Posts: 11
    hey yall i was wondering how i would go about removing the back seats (bench seat) in my 2000 jeep wrangler. ive done all i can think of (aside from actually un bolting it and tearing the carpet up). im pretty sure they come out, my friend told me they would (although he has a 97). if yall know anything about it lemme know, thanks in advance! :confuse:
  • The shaft that goes through the two "ears" on either side of the seat should have a small clip in a groove on the end of the shaft. Pull both of these off. Then slide the seat one direction the get the shaft out of the ear, then slide it the other way to get the other end out.

    This is easier to do with the top down or off. The seat is not easy to handle by yourself, try to get someone to help.

  • i replace the blower motor and resistor checked all the fuses and still no heat i can feel a little coming out but the blower wont kick on are there anything else i can check
  • I have an 03 Sahara with a manual transmission. I bought it new and it now has 71500 miles. Recently, when it is first cranked up the clutch makes a squeaking noise and tension can be felt when it is depressed. This feeling and noise goes away after a driving awhile. Furthermore, yesterday morning it did not want to go into second gear up or down it made a scraping sound. The gears move very freely while stopped and it the second gear issue does loosen up after driving awhile. I did have the transmission fluid changed this morning but nothing changed. The hydrolic fluid is fine. I haven't abused the trans., or been missing any gears...Any ideas, clutch not disengaging properly, synchronizer? Is there a problem with these trans that comes up a lot?

    Well here in sunny California we finally got some rain, so guess what...time to play in the mud. Long story short, got out of the mud went home to get some quarters for the car wash. The Jeep started up fine, went to the car wash to spray the bottom out so mud won't be flying all over the place on the highway. Started the Jeep and parked it at my in-laws to get the kids. Went out to the Jeep an hour later and found that I left my lights on.

    Tried to start the Jeep and it won't fire. It turns over but won't fire. First thought is the battery is dead so tried to jump it and still won't fire. Replaced the battery with a fully charged one and it still won't fire. I have a check engine light on so I check the OBD code...P0340 Camshaft position sensor error. Disconnected the battery for about 20min, pulled the sensor blew dry it, thinking I got it wet when spraying under the Jeep. Put it back in connected the battery, cranked up the Jeep and it still won’t fire. No engine light now...ran the diag, no error code now. Replaced the camshaft sensor with a working one and still no fire.
    Reading up in other forums it looks like the Crankshaft position sensor maybe bad as well. Replaced that one and same issue. Checked fuses, relays and voltages...everything looks good. up. Fuel pump is working. Checked coil rail and I'm not getting a spark. Checked the voltage on the coil connector and I'm getting the necessary 12v but it only lasts for about a second before it disappears. This leads me to the PCM not working. Tested my PCM and it works...how did I test it, my neighbor has a 2003 Jeep, plugged it into his jeep and it fired right up. Guess its back to the sensors. Still have a few more to tests out like the: ECT IAT MAP TPS.

    Any help would much appreciate. Not at a mechanic at all other then able to change the oil/plugs/and filters. Thanks in advance for any help!

    Key words in your post:

    1. Mud
    2. Water
    3. Rough run/won't start.

    Had problems like that too. Replaced the Throttle position sensor in 10 minutes after buying one at Autozone for 53.00. Non-issue since.
