A few weeks ago I replaced my crank sensor due to random shutting off and no start issue. Ran good for week or so then had a flashing CEL. Positive cable was found to be extremily loose. Scanned it and got P0352 code. Replaced coil rail then got P0300, P0301, P0302, P0305 and code for cam or crank sensor. Cant remember that code right off. When first cranks it runs 'smooth' then when heats up acts like maybe has misfires. Yesterday replaced cam sensor and again ran ok till hot and begins to stumble. What am i missing here? Could i have a PCM issues or what is my issue? Any input will be greatly appreciated. Thanks.

did you time the cam sensor correctly?

Yes. I put new one in exactly as the old one came out. It ran smooth for few minutes till got hot then started stumbling and acting up. While driving it isn't as bad, just stumbles badly at idle. And drinks gas like crazy now.

O2 sensors?

I am not the sharpest, but I cant see O2 causing P0300, P0301, P0302, P0305, P0352 and P1391. And, while driving down to road whether at 35 or 75 it makes plenty of power. Now my thinking is that with those misfire codes, they would have to be 'false' codes or the Jeep wouldnt run worth a damn on the road. I wonder if the PCM is getting whacky or do I have a wiring issue some where.

marklar probably has it right..

Google the toothpick method of setting the OPDA, get it in sync. It's a free couple minute fix so if it's not the culprit your not out anything but a lil effort.

Check temp gage to cpu. should have 2 wires to it. single wire is your temp gage.
