Jeep Wrangler Maintenance and Repair Questions (1997 - 2006)



  • tidester,

    I can't really say. The tires are 30" compared to the 28-1/2's that were on it new.

    I noticed the tendency to bounce right after I got them. I figured with bigger tires, I could get by with a little bigger foot print. It would soften the ride a little, not get me in trouble with wear, and would tend to reduce bounce. So, I really don't know how much mileage was affected by the reduced pressure. Remember also, the bigger tire size changed my odometer by about 5%, making it look like my mileage went down.

    I keep good gas mileage records. Correcting for the odometer error, I get about 14.2 mpg with all town driving.

    Tire wear is even and the bounce went away.

    Thanks, WD! I agree - the bounce issue would likely be a higher priority.

  • I have an 1988 yj with a 2.5 when starting and running gas shoots up and out of the side port inside of the throttle body .What would cause this? It shoots up about 6 inches or more. Any help would be great thanks.
  • Update- It happened to my wife yesterday. She was driving along and hit a man-hole cover...just the regular ones you see on the highway or back road. The Jeep immediately started vibrating, steering wheel shaking, front end vibrating as well as the front tires. It only lasts about 2 or 3 seconds. Naturally she let off the gas right away and after 2 or 3 seconds the Jeep returned to "normal."

    We cannot recreate the problem at will. It does not happen every time we hit a bump.
    One would think that if something was disconnected etc. that it would happen more frequently. I have a feeling that if I take it to the dealer they will not be able to recreate the problem and I will pay a service charge for nothing. I guess that is what I will have to do though. At least it will be on record in case something more serious happens. I just wish I could find the problem myself. Could something be lose or disconnected and still only effect it on once and a while? The jeep is stock and I do not know what type of suspension component would effect it the way it has I would agree that it could have been the brakes but this happens when we are not under braking. I was hoping that someone has had this problem and could tell me what the problem was. Thanks for your time.
  • My 2002 jeep wrangler idles at about 1500 at start up for about twenty seconds. Then it slows to normal idle speed. It has just started doing this. Any ideas. Thanks, JIM
  • Mine drops from 40 to 20 or as low as 10 psi after it warms up. I have had it in to Jeep to repace the oil pump and check the main bearing clearance. The chaeked and said my oil pressure really does go that low. I have 10W 30 in it now. Several differenct shops including another Jeep say don't worry about it, but I don't want it to sieze up when I'm in the booneys!

    QUESTION: Has anyone actually had one of these fixed? Jeep garage says a new engine.
  • My car is at the dealers right now. They tell me my problem is severely warped rotors and metal to metal brakes. As I said in other posts the dealership replaced the rotors a couple of weeks after I bought it because they had a "bad batch." How could they go so quickly? I hope they don't try to charge me for this. My jeep only has 16,000 mi. on it. Surely they do not go bad every 16,000 mi. What do you folks think?

    Not under warranty....364.00 out the door. I hope this does not happen every 16,000 mi.
  • I have a 2006 Unlimited, and had the rotors go bad at 7,000mi. The dealer fixed them no charge (like I was going to pay), and now at 12,000mi they're going bad again. Unfortunately I'd be happy with your 16,000mi. :-(.
  • This should be something that they fix at NO cost, especially since my 3 year warranty is not up. I think I will contact someone in consumers affairs in my state of Ct. I would like to know how many others have this type of problem and why most vehicles do NOT have this problem. There has to be some kind of defect.
  • Was wondering,,,have 33 inche tires on my 99 question is, if I go to 35's does the rearend support this...not sure if I have to change the gears before going to this size tire....Thanks
  • erickplerickpl Posts: 2,735
    With 35's, you WILL want to regear. Depending on engine and transmission, you may want to consider 4.88's. If you have the dana 35, you will want to reconsider strengthening it with alloy shafts (that have a higher spline count), or swap in a stronger axle.

  • vivonavivona Posts: 410
    This is an easy question. No answers?
  • They are fixing the Steering Shimmy tomorrow. It is still under warranty so no charge to me.
  • erickplerickpl Posts: 2,735
    600-750 sounds about right for my TJ. When it's cold, it idles around 750. As it warms up, idle goes down.

    I have 4.88's too and I can crawl down hills w/o using brakes at all. I also have 33" MT's. The issue that is the difference is the transmission's ratio. The manual's first gear is not geared the same as the first gear on the automatics, which would probably explain the descent down the hill is faster than you'd expect with 4.88's. I often have to GIVE it gas going down a hill. :)

    All that said, I have the 2.5L engine as well with stock t-case. Is it possible the IAC is misreading the idle speed?
  • I really would like to know more about your problem. I have a 2000, where oil pressure will drop to 10 on idle when warm. I am worried about burning up the tp end.
  • mac24mac24 Posts: 3,910
    The figures on your gauge mean nothing, it's the analog equivalent of an idiot light.. The gauge is just giving a representation of the oil pressure; low at idle, higher as the RPM increase.

    If you really want to know the actual pressure then connect a mechanical gauge.
    A cheap ($20) kit like this will do virtually any vehicle and be fully accurate enough for diagnostic purposes.


    O/P Gauge @ HF

    Why do you associate a perceived low oil pressure at idle with burning up the top end?
  • If I have low oil pressure, I am probably not delivering enough oil to keep the lifters, cam etc lubed, won't they eventually wear and freeze up. Am I worrying for nothing?

    I I disregard the oil pressure. What is the worst that can happen?
  • erickplerickpl Posts: 2,735
    Your engine will seize.

    Nothing major.

  • mac24mac24 Posts: 3,910
    Only worry when you have to. Oil pressure is much lower at idle than at higher RPM. It's also much lower when the oil is hot than when it's cold, and it's lower when the oil has been used for 3K miles compared to when it's just been changed.

    Use your gauges to establish a baseline for normal operation and don't get hung up on a particular figure. The time to worry is when a regular behavior changes.

    Finally, you could idle all day at 3-5psi without doing any damage as the engine is under the least load possible.
    If you want to worry about something, think of those soft metal crankshaft bearing shells that can be damaged by a careless fingernail, rather than the toughened and hardened valvetrain.
    Try not to let it keep you up at night though. ;)
  • tried searching for this, didn't see anything on them, 2 things:

    1) My blower control - recirc, top bottom, defrost etc - the vents - hardly works. I can turn the knob and if I'm lucky the air will come out of the speficied vents. At worst, the knob kicks on the AC compressor, but not the fans - even in the off position. I can't tell you how many times I've been sitting at an intersection with the top off and hear the 'click' of the AC clutch and have to wiggle the knob. The dealer, of course, can't find anything wrong. What I've noticed is it appears to be a vacuum issues. This controls are whacked first thing in the morning or when the engine is straining - hills, etc.. Any thoughts other than hooking up a gauge, but I don't know what it takes to run the bellows? (06 Unlimited Ruby, 6 spd man)

    2) Looking for tips on cleaning the inside of the soft top. When I fold my top back, the sails that fold in rub against the outside of the top and end up with funk ground into them. When I close the top the inside ceiling now looks trashed and I can't seem to clean the dirt out.

  • As I started typing this I realized how old the original message was, but might as well finish -

    Indeed, clocksprings are responsible for this. I found out becuase my older 99 had a bikini top. To install the bikini top there had to be a channel added to the header. The channel had slots cut out for the full soft-top latches. Well, when it rains the channel turns into a gutter and dumps water right on the steering wheel. I learned to flip the visor town to deflect the water to the floor. :P

    My blower control - recirc, top bottom, defrost etc - the vents - hardly works.

    Could be the switch which is a combined vacuum/electrical item, but it's worth checking the knob itself. They often crack and allow the knob to rotate freely while only intermittantly moving the shaft of the switch. Pull the knob from the shaft to inspect it.
    Very common problem with a very cheap fix! :)
  • Hi
    Please see my message #1242 on this board. I think it may fix your problem #1. Good luck
  • I have 1995 Wrangler. The blower only works on high. Where do I find the resistor pack and what else should I look for?

    I also need to replace the right speaker. Can I get at it by removing the glove box? I am hoping I don't have to remove the dash.

  • Bingo.. not sure how I couldn't find your original post by searching, guess I needed to be more generic.

  • The heater controls are from the same pile of junk as the rest of the heater/AC crap.
    I have a 1947 Willys CJ2A with the original heater rheostat switch.
    The heater core has been rebuilt and the motor was replaced when I converted it to 12 volt, but all the heater wiring is still original.
    Weird huh.
    I have had the blower switch on my TJ replaced 6 times so far.
    Replaced the console once. Smoked the wiring twice.
    MoPar still mean buy MOre PARts every day.
  • Hello all,

    I have the same problem - P2096 message on the MIL on my 2005 inline 6 cyl. Unlimited - 46,000 miles. I went to AutoZone and two other auto parts stores today and they cannot find the "P2096" Code in their system.
    Any help would be much appreciated.

    P0296 Cylinder 12 Contribution/Range Fault


    Um, cylinder #12 on an inline 6??? Something's whacky there!

  • My 98 Wrangler Sahara has an ongoing intermittent problem with the engine coughing and loosing power as I am driving it along. It can drive fine for days then on another journey it coughs, clonks and looses power. It has been investigated by my local garage but they cannot find the fault. Its had new plugs, leads, IAC and TPS but its still playing up.

    In 2000 it had a new oxygen sensor fitted at the time it seemed to be having similar problems and this cured it (on an old invoice we got with the car) is this likely to have gone again and be causing this problem?
