It keeps saying lost communication with pcm. It seems to only happen under semi heavy load. I cant really throttle the car hard the traction light will come on and it’ll misfire and start like stuttering. I did change some relays. Im really not too sure whats causing it. It also throws like every code o2 sensor speed sensor evap solenoid thingy when I put it under semi heavy load. I did change some relays.
Im not sure if it’s related but the alternator is kind of running on the low side like a 13.2 or sometimes go up to 14.2
Im going to check my grounds around the bay. Is there any particular ones I should look for?
