    Random multiple error codes and noise after engine replacement.

    At least on my '06, the PCM cuts injector control on a misfiring cylinder, not ignition control. The is an to prevent catalyst damage. A plug that fires in absence of fuel isn't going to cause detonation or any other problems.

    Rear windshield on 06' Liberty won't close and lock in most of the time.

    That flowchart is incomplete. A hammer needs to be an option somewhere in there :)

    Liberty down after flat tow

    If the input shaft to the transfer case is not moving, you'll be wasting your time tearing into the case. Crawl under there and see if the input shaft is spinning when trans is in gear and a helper hits the gas. Lift all wheels off the ground, obviously, in case it decides to start working again,

    2005 AC Help - What am I doing wrong?

    First off, a/c flushing should, at most, only be performed on the evaporator and refrigerant lines that are free-flowing/not have anything like mufflers, filters, orifice tubes, etc. on them. Both should be removed from the vehicle when flushing to ensure the solvents are fully drained. Blowing...

    Liberty down after flat tow

    NP242 (Selec Trac) has neutral- and all selections that NP231 (Command-Trac) has for that matter- and adds a full-time option to the mix.

    Liberty down after flat tow

    Does it matter what gear the transmission is in when when towing like that?

    Engine swap stumbling badly 2002 KJ 3.7 2 Whl

    I don't think a clogged cat would cause a misfire. If you have a scope, you could back probe both the injector and ignition coil and compare waveforms to another cylinder. Checking compression on 3 wouldn't be a bad idea, either. If you don't have a scope, take a resistance reading on 3's...

    Radiator leak by drain plug

    Mine leaked at the same location. Maybe it's a common failure point. I tightened the petcock to no avail and just ended up replacing the rad. Not a hard job.

    Misfire

    Don't buy any ignition coils just yet. Ignore the O2 codes for now, especially if your miss occurs even when the engine is stone cold. Swap #4 ignition coil with one from another cylinder, erase the codes, drive vehicle and see if the misfire changes cylinders. If no change, do the same with...

    Misfire

    You may have a bad PCM. For some reason, #4 ignition coil control is the one that gets fried. Happened to me a few weeks ago. I'm assuming you don't have a scope. Do you have a multimeter that can read frequency (via the test leads)?

    2005 Liberty Jeep Limited

    You're dating yourself, seafish, if you actually remember the good ol' days when diesel was cheaper :) The gas crisis of the 70's made the public and car manufacturers consider diesel as an alternative, as it was significantly cheaper at the time. Car manufacturers rushed either new engines or...

    Need PCM - Need some information- 2005 Jeep Liberty Diesel

    If the diesel PCM is in the same location as the gasser, it should be under the hood behind the battery bolted to the inside fender. Not hard to get to and easy to take out. You'll most likely need to get the part number off it and match it up with the replacement unit. And, yes, the PCM would...

    Engine runs rough after an hours worth of driving

    PCM is attempting to add fuel to a perceived lean condition, based on O2 feedback. If you were getting fuel in through the purge solenoid, you would have a rich condition and your trims would head the other direction. +32% is a high number. Since your problem is occurring on both banks that...

    Misfire woes

    Thanks for the suggestion. I ended up going with one on eBay, just a little while ago. Only around $70, which includes programming- almost 3X less than what Flagship One wanted. We'll see how it goes. After talking to several people about it, apparently the most important thing is to make sure...

    Misfire woes

    Thanks for the detailed reply, dtennes. Yes, I'm still throwing a misfire code, which is expected since the cylinder is still misfiring. I'll give your idea a shot and clear the code/touch the cables together and see what happens, though I don't have much hope it will work. The connections on...

    Misfire woes

    You were right on the money, reload40s. Bad PCM. Specifically, a bad coil driver, I imagine. I scoped the ignition primary on 4 and got no ground control signal. Traced the wire back to PCM, tested from there and still got nothing. I've been hitting ebay for a "plug and play" programmed one...

    Crankshaft position sensor

    You ought to test the sensor before just condemning it. Just because you have a code for it doesn't mean it's faulty
