Like you guys gave said previously check fuel pressure etc all is good, I checked all the grounds. Everything seems to be good, now I got a bluetooth code reader and did a live test, while driving the RPMS read like they’re supposed to, the long and short term fuel trim reads how its supposed to, my ignition timing reads at about an average of 302ish. I havent replaced the PCM because I would like to keep the tunes to my PCM. The flash tuner I had the screen was broken and it was the SCT X3 which SCT doesn’t support anymore and the guy who would have the email of the tunes is unfortunately dead now. Im trying to really avoid replacing this PCM. The exact code Im getting “P0320” but this time its saying “PIP Circuit Failure” instead of “Igntion etc etc etc..” My coil wires are in tact and my ignition coils got replaced which helped it for a little bit. And like I said previously both the CPS and CKS have been replaced. What else could this be and again like I said previously is there anything from me doing my heater core that could have caused this?</p></blockquote><p></p>
