Why do I keep getting code for PCM AND TCM.
My car keeps stalling when I slow down or come to a complete stop. It’s a 06 charger srt8 with a NAG transmission. I keep getting code for PCM AND TCM I don’t think those are actually the issue. I’ve replaced PCM and it worked for a short period of time and now it’s back to idling poorly and dying while idling/ coming to a complete stop. And sometimes it only idles at 500-600RPM AT A LOSS ON WHAF TO DO I don’t want to take it into a shop
