Greetings, Have a 1989 YJ with the 2.5l TBI. Have had a sporadic idle, stall problem. Verified fuel delivery and injector performance, tested and/or replaced all sensors and IAC motor. Cleaned throttle body, checked for vacuum leaks. Kept looking over at the coil/icm assembly, but thought "no, just replaced those not too long ago." Long story short, tested the coil - badly out of spec. Changed out both coil and icm and finally (slow learner here) checked voltage entering coil. Constant 14 =/- volts at startup and run. Checked with my daughter who drives the vehicle and she confirm -
Hi, I've been hunting and chasing my tail to get some kind of throttle response from my wrangler above 45 MPH. I know these are not very powerful to start but I feel like what I'm experiencing is abnormal. Anywhere above about 45MPH when throttle is given There is little or no response from the engine. I have gone through the tuning and troubleshooting, replaced numerous things and adjusted what is able to be adjusted to the best of my understanding. Most recently I put a new cylinder head on due to a cracked web between valves on cylinder 4. I was so sure this was going to solve my -

Hello to All.... I wish to thank all the members and especially you Mr. Ludell for all the time spent on our endless problems....

The current problem started on an outing in the woods ..drove fine climbing, downhill and 4wd.. coming back the engine began to act like it was -
So this is a wierd one, I've looked and looked on the Internet and can't figure it out. My jeep wrangler runs and drives just fine but there is no cel on start up. I know there should be code because I have no 02 sensors hooked up. I want to know if there is more though. Any help would be appreciated -
Hello all. I have a 1990 jeep wrangler with a 2.5l 4cyl engine. The engine is young, only 4 or 5 thousand miles on it. However the rest of the drive train has 264,000 miles on it. Anyway the saga continues after adding new rear leaf springs. After the replacement on the way home this noise happens only when I let off the throttle. I think the ride hight is higher than what the stock was. But that should still not cause this noise Right? My question is what the stock springs should be just to verify I have the right springs and and what the awful sounds coming from the transfer case. Transfer c
