Jeep Wrangler Maintenance and Repair Questions (1997 - 2006)

    It's the breather hose. It mounts in a clip on one side of the radiator- the driver's side I believe.

    Yup, just behind the radiator overflow. Just ziptie it up there and drive on. :)

    I have a 2000 Jeep Wrangler and every once in a while when I start it the blinkers, windshield wipers and radio won't work but the hazard lights and headlights work. Most of the time they work fine. I am clueless. Please help and thanks to the genius that can figure this out.

    Had a similar issue on a BMW I had purchased. Problem was in the cluster control unit (not sure if this is the PCM or not). It ALMOST sounds like you have a loose ground somewhere. The wiper and blinkers are in the same assembly, so if you can trace that down, I wouldn't be surprised if you found a common ground point with the radio. There are a few known grounds on the TJ. One is up under the driver footwell against the side. Check there for any loose wires screwed to the tub. I'm sure Mac could point out other locations, but your symptoms being occasional has me thinking loose/bad ground.

    But I am NOT an electrical expert. :)

    I have a 04 jeep wrangler sport 6cyl. The engine runs rough and I get a engine code 0303 miss fire # 3 cyl. I ruled out the injector is there any way to check the ignition coil pack.

    Thank you for your help.

    Hello, I have a 97 Wrangler TJ, 4.0L, manual tranny.
    Several months ago, my Jeep sounded like it was tumbling rocks, thought it could be Catalytic Converter, never had it checked out as it finally stopped after a few weeks or so. However, now I have a new problem that just started, after the engine is warmed up, it will begin to sputter randomly at cruising speed, the tachometer will sometimes drop to zero, and check engine light blinks on for a second, then it will run fine for a little while longer. Now today, it has gotten so that it actually stalled on me twice for a split second while down shifting to 2nd to turn a corner. When I push clutch in and rev engine without turning ignition, it will come right back to life again....I believe it did pop once. Then it did it again right down the street.

    Do you think this could be the Catalytic converter finally dieing and causing this, or do you think I may have an entirely different issue? Perhaps, ignition on the blink? We have not checked for a code as of yet with an OBD. Why? Because my husband is tired of working on my Jeep! :blush: So, I've resorted to asking some experts here on this site so that I have something intelligent to ask him to try next! ;)

    We've just replaced all plugs, cap, rotor and wires just yesterday to see if that would help. All of the above looked in good shape, not really needing to be replaced. No loose or frayed wires anywhere, battery and cables all good!

    Quick side note; I have 37 inch tires, was having issues with ABS. Disabling the ABS system shouldn't have anything to do with this stalling issue correct?

    Thank you in advance for any suggestions and help anyone can give. :shades:

    I have a 1997 jeep wrangler. While driving today my battery guage shot to the 19 and the check guage light came on. Any idea what this could be?

    There is a recall on catalytic converter on 97 wrangler. I just had mine replaced, I was having the same problem.
  • maryp001maryp001 Posts: 4
    Hi. My 1997 Jeep Wrangler is having the same problem. Took it to 2 different mechanics (jeep dealership) and they can't figure it out. Did you ever figure out what it was? I love my jeep (my second) but it's been really having so many issues this year. wow.

    Hi. I have had a bunch of problems with my 1997 Wrangler lately.

    First, it would crank but not stay running unless I kept my foot on the gas. At the same time while driving, the battery gauge would shoot up to 19v and check gauge light would come on.

    The only trouble code from the PCM was the o2 sensor. Changed that along with a recall on the catilitic converter. (Alternater/regulater was fine). Changed the battery as well.

    Now it runs fine but battery gauge still shooting up to 19v every now and again.
    I have had it to 2 different Mechanics and they can't make it shoot up and there are no trouble codes.

    I have heard of a couple of people having the same issue although they sound unrelated, but have not heard out come.

    Any ideas?

    Hi! This is my first post and I hope you can help me as much as you've helped everyone else!

    I just made an appointment with a local mechanic to have a diagnostic done because the engine light just came on. Before I hear what he has to say, I wanted to get your opinion.

    For the past couple of months when I start my 2003 wrangler sport automatic v6 it makes this banging noise for a few seconds before it evens out.....then it drives fine. I didn't know if this is some type of misfire triggering the engine light.

    The only other problem I've had recently that might have contributed to the engine light is my battery dying due to leaving my sirius radio on (old battery....needs to be replaced). When i jumped it a couple days ago i had to leave my foot on the gas to keep it from stalling. I finally let it stall out and started it right back up and it was fine.

    Also, the Jeep dealer (they went out of business and i'm not gonna shed a tear because the mechanics were pushy and never did anything right!) said it was necessary to get a radiator flush for maintenance. At almost $300.00 I wanted to make sure I needed it before i did it. My jeep has 69,000 miles.

    Help! I'm not mechanically inclined so some guidence would be great. :blush:

    I have the same problem with both my AC and my heat in my 03.

    Thank you for the info. I've tried finding info for a Cat recall online, can't find anything so far. I do believe you though, I've heard a few people mention it. However, I did pass smog, so not sure if anything is wrong with Cat or not...would still like to have replaced if recalled.

    We did finally solve the issue with the Sputters and Stalls....for anyone else wondering, it ended up being a loose wire on the Crank Shaft Positioning Sensor. Fixed that and it runs like a champ once again!

    I had a 93 Cherokee automatic, a few years ago back that would suddenly stall and not restart for about 10 minutes. Chrysler couldn't tell me why this was happening, even though my life was in serious danger, as it would randomly stall even in the middle of the freeway!! One lady was killed in her Cherokee on the freeway due to a stall like this.

    This serious incident ended up being the Crank Shaft Positioning Sensor as well...Only a $100.00 part from the dealer!! Not worth one's life...very easy fix! For anyone else having similar problems...check it out.

    For some reason, Neither one of my vehicles would not show a code for this problem on the OBDII. But once replaced, they both ran perfect!

    I have 1999 Jeep Wrangler TJ, 2,5L 4 cyl. Two hoses are connected to the top of the valve cover. One of them has oil on itself on the bottom where hose go to the engine. Same rubber hose has plastic one inside. What is the name of that hose?
    So far not much drops of oil on the floor in my garage, but......

    Hi.. I have a 2003 jeep wrangler and i love it except it jerks really hard sometimes and after i drive it for over an hour or so and come to a stop and then go to take off it hesitates likes it out of gas or something. I want to fix it but nobody knows whats wrong with it .I took it to a tranmission shop who charged me 300.00 to clean all of those little parts and peices in there that worked for about two months , I always have the oil changed when i am suppose to , add fuel injecting cleaning stuff when i fill up with gas , I know nothing about this stuff but even my honey and his friends can't figure it out . please if anyone knows how to make this go away please let me it is driving me nuts!! :confuse:

    Both hoses are crancase vent hoses. Hose #1 sucks oil fumes from the crankcase via the valve cover and into the engine to be burned. The oil fumes are replaced by clean air from the air filter via hose #2. The direction of flow is shown by the red arrows.

    It would appear that the problem is connected in some way with whatever the transmission shop worked on as they fixed it, if only for a couple of months.

    Go back to them and check what was actually done in detail.
