My friend has a 95 XJ that has us stumped. Once in every 10 or 12 starts, it runs like a clock from idle to redline. The rest of the time, it stumbles, shudders, lopes, back fires, and runs like crap. We have replaced every sensor at least twice, the computer 3 times, the distributor and cam...

Friend of mine is working on a 95 Cherokee Sport 4.0L, automatic. When he got the Jeep, it would not run. He replaced the crank sensor and it now runs, but lopes badly at idle and backfires thru the throttle body and exhaust when revved up. Very sluggish pick-up. He has replaced the crank...

I posted awhile back about my 88. 4.0L, b/a10 5 speed. It would skip,miss, and die at random. If cruising, when I pressed on the gas it would stall out momentarily and then catch and run fine. This all started when I put in a new short block. I changed out the usual culprit sensors from my...

I know that most Jeep owners are pretty fair mechanics and do not like paying the high prices for new parts or someone else's labor. Mr. Mike Rowand has posted an extremely well written article on how to DIY. Check out the link below and see how easy this is to do yourself...

It's that time of year again to take care of our cooling systems, so, out comes the hose, the flush, and new anti-freeze. I was thinking about using the removal of the temp sensor to bleed air out of the head, and came up with a system to do a complete flush. I installed one of those pressure...
