My mil came on and I scanned and got a p0352 code. I got another coil pack and erased the code but that did not fix the problem. Ran it for about 5 minutes after erasing code and replacing coil pack and I still have this code. What can I do to fix this. It runs good while its cold but when she got up to operating temp is when it acted up by skipping and throwing this code again. It idles rough and when the gas peddle is pressed it sounds like its skipping. Spark plugs new, good fuel pressure. Resistance on injectors are good. Cam shaft sensor is new. Egr valve is working. Replaced timing belt a month ago and it ran fine after the timing belt change.

First, check to make sure you are getting 12 volts to the coil. Also, follow the wiring back to the PCM. Check the connector to make sure there is no corrosion or damage to the pins.

Let me know what you find.

I did check the 12 volts and the 12 volts is present. I traced all the wires back to the pcm. Someone said it could be the pcm. If I get one from a junk yard will I have to have the pcm erased or reprogramed for my car or can I just plug the pcm in?

It could be the PCM. Before getting one, make sure the wiring has continunity. Also, make sure if you get one from a junk yard, it has to be from the same year make and model. YOU MUST make sure that the part numbers are the same or it won't work. If you get a good one with the correct part number, you should be able to just plug it in and it should work.

Let me know. Also, and you may have already done this, check the pins at the PCM connector. They are known to push into the harness and not make contact.
