    fouled spark plug

    Yes, a 15-year old thread that was resurrected 5 days ago by a person with a similar problem.

    Pictures of Tomken Rocker Guards?

    Interesting link from gearwhine! From 2003...when I installed the Tomken sliders on my XJ Waggy. I've had some hard hits on them and they have held up great for the past 16 years. Just my experience though.

    Front Drivers side pop when braking in reverse?

    My money is on the lower control arm. Stick your head out of the window and watch front tire as you reverse and brake. I bed you'll see some movement.

    Poor Braking Mystery

    When you have the "wet brakes" feeling, how is the pedal? Is it still hard, but just no breaking? Is it soft...like it goes to the floor? Does pumping the brake pedal help?

    TV cable needed with manual shift aw4 ?

    I'm confused...what is a "manual AW4". Does the OP mean manually shifting an AW4, or is OP referring to a manual (AX-15) transmission?

    No power jeep holding back

    I know you said you replaced the fuel pump, but did you check the fuel pressure at the rail? Really sounds to me like a fuel delivery problem.

    Shifting into 4wd, newbee?

    Not sure what prompted this resurrection of an 11 year old post, but there's a LOT of bad information in the thread! Wow. Both the NP242 and NP231 can be shifted into and out of 4High while moving at legal speed...up to 55 mph. Just back off on the gas and shift. It's only when going into or...

    Looking for Select trac cv joint axle

    I don't think the NP242 came paired with the front axle CAD. My '89 has the 242 and a solid passenger side shaft...and has regular u-joints, not CV joints.

    High Pitched Sound From Engine At High Temperatures

    I'd look for a vacuum leak, or possibly a throttle body gasket leak. Engine produces highest vacuum when throttle is closed, and lowest vacuum at wide open throttle.

    Shifting AW4 into reverse while going forward

    I'd put my money on "it needs to be burped". I know you are aware of this issue, but I had similar difficulty with my '89 after blowing an upper radiator hose. Did repair on the highway with new hose and couldn't, for the life of me, keep it from spewing out the fill bottle. Finally, after...

    Stock 99' XJ Memory Steer 140k miles

    Have you been adjusting the set screw on the steering box? Some people adjust this screw in an attempt to tighten up the steering. If it's too tight, it won't self-return to center.

    Clunk/lurch into Drive, but not Reverse

    Have you actually been under the Jeep when someone is shifting to see where the noise is coming from? If it that loud and that noticeable, you will have no trouble ascertaining what is making the noise. As far as the slip yoke "sliding down" due to gravity. It cannot happen! The rear...

    Surge, loss of Power, Dies. 90XJ RENIX 4.0 Auto

    Anything you recently did, especially right before an issue, is suspect as related to the problem! That being said, that sounds to me like a vacuum leak, which would make it "surge"...idle high as well.

    Diagnosis? Front Driveline Clunking

    As a clarification, the car should not move in 4Full Time with on of the drive shafts missing. 4Full Time utilizes a differential between front and rear output shafts...this is why you can use it full time (all the time, even on dry roads). 4Part Time should not be used on drive pavement, but...

    No Crank, No Fuel, No Start, All Sens Pwr'd

    ^^^ All good advice from 8Mud, but I've got to wonder. Consider the sequence of events, changed TPS, IAC, and CPS and it worked great for a day, then began to run poorly. What would cause that to happen? Poor connection to one of the recently installed sensors? Poor adjustment or fastener...

    AW4 transmission troubles

    Just to clarify for you...the transmission leak is not at the SYE. The transmission and transfer case don't share fluid, and the SYE is on the transfer case. Look for your fluid lead somewhere else.

    Renix crank no start

    so you've verified fuel pressure at the rail and spark at the plug. You should also verify the injectors are firing (use noid light). also suspect it may be flooded. Try cranking with accelerator to the floor (not pumping, held at WOT). This will turn off the injectors and allow the motor to...

    Hidden air tank

    don't forget you'll need access to the tank to drain it of condensation (to prevent rusting).

    Axle Identity

    The oil seal for the D30 is at the pumpkin. Not sure what you mean by "outer" seal. The only thing on the outer end of the axle tube is a dirt shield, doesn't "seal" anything.

    Renix Cherokee Idling Issue

    Not to hijack this thread, but I have a similar issue, but it is intermittent. On some starts mine will idle high (2,000+ RPM) and won't come down. If I shut it off and re-start it, it will then (most of the time) idle normally. ASD relay as well?
