x2 on the tire imbalance. Tires out of balance usually have a wobble zone depending on severity and placement. I.E. between 45 and 55 mph

 

Jack it up and spin the wheels/tires, look for any out of roundness, that'll do it too no matter how slight

 

Sorry for the delay...I got stuck working 16 hours yesterday...I checked it out, and yes, it does struggle a little bit around 20-25 MPH, just nothing as severe as the higher speeds. Suspension was actually just fixed a couple weeks ago along with "new" used tires being balanced and aligned. This made no difference. The Seafoam may have been completely irrealavent, I just like to provide as much info as possible! Still sound like the Throttle Position Sensor?

 

I will try this! Thank you!

 

Hey. was wondering if these rims and tires will fit on my stock 1992 xj. http://abbotsford.craigslist.ca/pts/4929572643.html i know the bolt pattern is the same and from what ive read the tire shouldent rub but what about the backspacing? thanks

 

Is the stock downpipe 2.25" ID or OD ?

 

Pipe is always sized by I.D.

 

Same as what you have (assuming yours are stock)

 

Not sure if a driveshaft u-joint would cause this, but it wouldn't hurt to check it if you haven't.

 

Hey so for those of you who don't know I have 3 xjs, the black jeep which has been my donor vehicle, the red jeep that has been my off road toy / work truck for the last 8 years and last week I bought the silver jeep. It's going to be my new work / play mobile. its a 2000 xj, not to crazy about the idea of coil packs but it is what it is right? So I was messing around under the hood last night actually changing the purge valve when I noticed a module on the inner fender right up by the fire wall. My other 2 jeeps are 99s and they don't have it. The wiring to it is totally factory. Any ideas about what it is? I did a quick search but I haven't found it yet

 

Pics?

 

for what ever reason pics aren't uploading from my phone

 

don't see any pics

 

Yeah for what ever reason it's not working?

 

So going to look at a 93 xj and a 95zj for my brother tonight. I'm an expert at 97+ xjs but new to pre 97s and completely new to zjs what should we look for.?
