Does anyone have the engine control schematics? I’m going to be working on it this coming weekend for a friend they said the red lightning bolt is on the dash with no throttle response. I used to have access to service information but not anymore. They’ve been told it needs a pcm from dodge if it does installation of a new one and programming for me is not an issue
