Stalled in the road after getting gas a few days ago. Wouldn't start back up. Towed it home. Replaced some sensors, coil pack, etc. After returning all of the sensors, I noticed the fuel injector fuse had blown. Replaced it and it started up for a few seconds but with clicking coming from the...

About a week ago at the gas station, I got back in and had no power at all when I put the key in. I 'tightened' the connections to the battery (which were not loose) and it started right up. Yesterday I got gas and drove about a mile and it stalled as I slowed down for the red light. Wouldn't...

2002 TJ 4.0 I first noticed it at red lights. A grinding/rattling sound coming from beneath me that disappears when I go into neutral. And it's not noticeable when I'm driving, probably drowned out. I've been leaking ATF for a while but I thought it was just a bad pan seal and now it has low...

About 3-4 weeks ago my shifter wouldn't move to Park, I had to slam it forward. This happened intermittently maybe 3 times before... about two weeks ago I was going 50 MPH and my jeep bucked. I reproduced the way it felt in a parking lot by going slowly, and very quickly (without taking my foot...

About two weeks ago I was going 50 MPH and my jeep bucked. I reproduced the way it felt in a parking lot by going slowly, and very quickly (without taking my foot on the gas) shifting into Neutral and back into Drive. So this made me think the Transmission had slipped. This happened one more...

It is frustrating that the TJ is so vulnerable to problems with its 'computer'. It seems to me that a computer represents the antithesis of what a Jeep is supposed to be. Rugged, utilitarian, able to be repaired in the field with blood, sweat and duct tape. I would like to be able to brag that...

So an open circuit code is supposed to mean an injector is getting a constant signal to stay open. Usually a ground somewhere in the harness. Could also be a bad injector or a bad PCM. We know this. And let's say all the plugs/injectors are getting power, all measuring the same. Wires all test...

I removed the valve cover to get to the springs and for laughs I also snapped off the PCV valve while working on the catch can. Bolted everything back up to drive to O'reilly. It clearly wasn't running all 6 cylinders, was shooting oil out of a place that, well, was already leaking a little but...

Hi guys. Just joined, been reading for years. I need a PCM for my '02 and I was told by a mechanic who worked at Chrysler for 7 years, familiar with the 4.0s, that I could <technically> go to the yard and pull one from any other 4.0 (Cherokee, etc) and it would code, but it would fire up. I've...
