    It's very simple to clean using some carburator cleaner and a wire brush. It can be just as reliable as a new one after this treatement. The dealer will quote a price of a couple hundred dollars for a new one, and about $100 to change it for you. Hey, they gotta make money some way. But yeah, its very easy to replace or pull and clean. Just be careful not to damage the graphoil gasket, it's pretty delicate.


    When mine was acting up, I got the CEL and a rough idle. Never bad enough to completely stall, but enough to notice it wasn't normal.

    You can actually order it from autozone online. Check out it says it's the whole valve for $119, and tells you to clean out the chamber of carbon. I am going to get one for sure as I've been throwing an EGR CEL for a while.

    The new EGR from the factory comes with a new gasket. Or you can get a new one from the dealer for about $10. Given that it is virtually impossible to get an old EGR off without pulling up some of the gasket, I'd spend the $10 on a new one. Otherwise, you are just setting yourself up for a new air leak.


  • Just picked up a very nice 2000 S 4WD with 74K miles for $8700.It's a daily driver now,but will be retired to "weekend adventure vehicle" in a year or two.I hope to literally keep it forever.


    Just one problem.The beast won't run on regular,and I even get a little valve clatter running 102 octane? Could it maybe need a valve adjustment?


    thanks in advance,


  • paisanpaisan Posts: 21,181
    Has to do with your oil, not the octane fuel IIRC. If it has to do with the octane then your knock sensor is probably broken and not retarding the timing properly.

    Or pinging/knocking?


    If pinging, also check the EGR thread above.

    1988 Trooper, AUTO trans. , 165,000 miles....just had an idle quality problem corrected with new idle air controller, new EGR valve and a few other pieces replaced. The temp gauge was not registering reliably(showing full cold most of the time)at the time and now shows full hot all the time. I've replaced the sending unit with 2 new switches with no change. The major problem we have is the 4 sp OD trans will not shift into OD range even when warmed up. Is this related to the sending unit signal problem? Garage thinks its an internal valve body problem but I don't buy that. Anyone with any experience with this and suggestions would be appreciated.
  • Sounds like cleaning the EGR is the place to start since there is no cost involved.Where is the knock sensor,and how much do they cost?Is there a way to test this componant?


    Thanks guys,


  • Yep, I've put it off for months, but it's now time that I did it!


    Based on a lot of horror stories (CEL lights) related to spark plugs that are not Trooper - friendly, the consensus seems to be that only OEM Denso's should be used. The user manual for my 2001 LS lists "two" Denso's -


    K16PR-P11, and

    PK16PR11 (cheaper, and easier to find)


    Does anybody know why I shoudn't use the "PK" version of the plug?
  • FWIW, I went with the NGK's without any problems.

    Recently bought a 2000 Trooper and have been considering new tires. Wanted to go to a 245/75/16 due to value for $ but is there any problem with the hard spare cover fitting over the taller size, because I want to change the spare also?

    I changed mine out last year between 65,000 & 70,000 miles. I used the Champion RC10PYP4 that turned out to be the same as the original. Worked pretty good.


    One note, I figured out a way to deal with the rubber boots without tearing them. Use compressed air or a pump with one of the little adapters for blowing up air matress, etc. The boot pops right off.. I figured that out after the 6th one refused to release it's grip on the plug and I thought I might tear it... Only sold as a set with the coil from what I hear and over $100 for the set.
  • Thanks for the air pump tip. I was gonna try that, 'cause I remember reading a previous post about it.


    I'm thinking I may try those Champions myself. That plug is also recommended in my owner's manual, and I can get 'em for $4.00 each locally.


    BTW, I just ordered a serpentine belt from St. Charles for $17 - dealer wanted $79 for the part and labor. Replacing it seems too simple to pay them that kind of money. At 47K, the belt has a lot of cracks on the ribbed side, so thought I'd be better safe than sorry.
  • For those of you considering replacing the serpentine belt on late model Troopers, here's a belt routing diagram -




    Yeah, it is for an Amigo, but it's identical to my '01 Trooper LS.


    Since it is apparently such a piece of cake, I'm gonna be doing it this weekend. The diagram is important to me, just in case I get confused about the correct routing after I take off the old belt.
  • The hard cover and the soft cover before that, only fit the original size spare tire, 245/70R16, and no other.


    I replaced the spare also with a larger tire, and the hard cover lives in the attic.


    I am considering the LT245/75R16LRC tire for more tread depth and a stiffer side wall, I like a firm ride. The Revo in this size has tread as wide as a 255/70 and is as tall as a 265/70. The LTX M/S does not have a LT245/75R16LRC, and the LRE is very heavy which means poor MPG and acceleration, but very long tire life.
  • hi,


    i'm curious about what the "idle air controller" is - my 98 trooper has been having a problem where when cold and stopped in traffic the motor is revving fairly high - if i pop it into neutral it revs at 2000 revs - if its in drive its pushing fairly hard on the transmission and revving to 1200 or so... this morning i took off a wire to a sensor which is right on the air intake at the very front of the motor - it solved the problem instantly!! what did i disconnect? was it the "idle air controller" you talk about? the engine check light came on a few minutes later but the car is still running perfectly.


    any ideas?


    thanks for your help.

    Yep, this is a temperature related problem. It has to get up to operating temperature for that O.D. to kick in. Something is wrong with the sensor or the ECM. Its odd that the temperature gauge is pegged out all the time. That could be read as a bad sensor to the ECM which might prevent the O.D. from coming on.
