What is the "brand" (i.e Bosch Motronic, etc.) of the ECU in a 98 xj with the 4.0. Has the california emissions package as well. Anyone know how to hack into it? Any dtc checking programs (I've asked before but cant remember where). Kinda vague but any help is great.

Anybody know some good freeware for our jeeps? I have a vagcom cable (for vw's and audis) but I guess it works as an interface for our jeeps. Mainly looking for something to figure out and possible erase p-codes but it'd be cool if there was something I could tweak the jeep a little. Thanks in...

Anyone use this on any of their vehicles? Anyone with a vw 1.8t in particular? A friend of mine has his for sale for a decent price so I was gonna pick it up but was wondering what you guys thought about it. I did a bunch of reading but it cant hurt to get personal opinions, problems, etc.

Looking to sell a few things for cheap. I've got my old system, bought it off a friend a while back, its a lightning audio amp+subs in a box. Don't know many specs on them but they are 10" and i believe 500 watts each. The amp is a 150x2 channel but it matches up pretty well and sounded great...

How easy is it to foul a cat when you have a misfire (just never fires)? I figure with an extra cylinder's worth of fuel not being combusted sure could hurt the cat. It smelled like rotten eggs.....any thoughts?

Dunno if he's on here but I meet a guy in a red commanche running at the dragstrip last night. I believe he was from RI iirc. Ran low 13's. He said he's got 9.25:1 CR with .060" pistons. I guess they aren't allowed to modify much and his engine bay was fairly stripped down. Stock tb, airbox...

Dont have a part number, will look for it later but if you want it for $30 o.b.o. then let me know. It's by springfield, ma and you gotta pick it up or meet close by cause gas is expensive.

Anyone have any recommendations for software so I can read/log whatever my vehicle does? Only ones ive seen online look kinda shady. I've got a cable already but I can't exactly plug it into my computer because I doubt I can read any of it. Im not looking for expensive software but just...

Anyone have the latest part numbers for some high flow cats both with and without bungs already installed? Mine is kinda shot now so I want to get a new high flow one. How much of a difference from a high flow cat vs. oem replacement? Hopefully these things are under $100 shipped. It's a 98 with...

It's on a stock 98. It's been slipping on the highway, sometimes worse than other times. The fluid isn't smelling the best (just recently), and it makes metallic noises. I had some trouble making it up a hill on the highway today (slipped it as little as possible and pulled over when safe) and...

In no huge rush but looking for a replacement for my chrysler 8.25 in good condition. LSD would be nice but another open diff is fine. I know there are a few at the local junk yards but you can't tell the condition 100% + spare time is an issue. Shoot me a pm or leave a message here if you're...

Anyone have a spare engine dipstick laying around? I basically break everything I touch when I work on my jeep. It'd be for a 98 4.0. Does anyone know if there are different styles for different years because I might bum a ride to the junk yard if need be. I can meet around worcester,ma or...

On my 98 4.0 aw4 xj with ~115k miles on it makes a hissing/slight whining noise when Im light on the throttle. Between the engine and transmission there is a decent amount of fluid caked onto the bellhousing cover. I cant tell if the noise is coming from the cat (possibly clogged) or the...

http://www.youtube.com/watch?v=g0aBhenL51I&feature=related Anyone ever see that before? Looks pretty cool but doesnt seem fast at all, maybe he just wasnt pushing it 100%.

It's a 98 4.0 ,231, d30/chrysler8.25 no lift. I just bought two new tires in the back that match the fronts and they balanced the wheels too. I changed the diff fluid last night and during that I checked all the gears and pulled out the axles shaft. Got everything back together and it still...

Its a 98 with the 8.25 and no trac-loc. Do I have to remove the drum brakes to pull the axle shaft out? I just want to check the bearings because something sounds bad back there and dont want to remove the drum. Thanks a lot.

And how many of you have broken your shocks bolts? Im thinking about doing a budget boost and with it installing some new shocks. Something else I was thinking of was to have sears install them for free....but if they break it im not sure what their remedy would be. I might just pb blast the...

When my jeep (98 4.0 aw4) is warmed up, it idles ~800rpm and uses .8-.9 gallons per hour of fuel. However, after a cold start itll be at 1.5gpm till I start driving it around. I let it warm up for a minute today, and drove a couple hundred feet and it got into closed loop mode (at least...

Looking for a 4th generation vw with either the 1.8T or the TDi. Will consider VR6 but not a 2.slow. Would love to find a cheap TDi but haven't seen many. Needs to pass mass inspection too. Prefer a standard as well.
