So I'm new to this forum and have seen a lot of people with a P0352 code. The 2 main fixes seem to be to R&R the coil packs and if that doesn't work possible the PCM.
This is a long post but so I'll get to it. I have 95 with a 2.3L, manual trans, and 4 wheel drive that was given to me. I did not have the P0352 code at this point but my fuel economy was crap so I cleaned the MAF and the Pressure sensor that is in front of the throttle body. Since both of those components were very dirty I decided to check the plugs and wires.
The wires came apart while removing them, and all but on plug had normal but severe wear. The odd ball had a ton of corosion at the connector. I had also had an emission code that ended up being rotted vacuum hose at the purge valve. I wasn't very confident about drivers side cyl 3 and 4 plug wire connections but it seemed to run fine. The next morning I had a P0352 immediately after starting the engine.
My main question is can a bad plug wire connection cause the P0352 or is this code only from the coil and PCM. If you say it's the coil or PCM please provide pinpoint tests so I can verify which is bad. I checked resistance on the secondary circuit of the front coil that controls the intake side and it was within spec.
I am not a parts changer unless I can verify the issue before replacement. If possible please help me out with this. If more info is required let me know. Thanks in advance.
P.S. told you it was a long post.
