Hi all! I have a 2006 636, power commander v with aftermarket exhaust. I’m having an issue where it starts running poor after hitting a bump, won’t let me go over a certain rpm, usually like 5k. I can pull over and turn the key off and on and it’ll run perfect again. Headlights and dash will also flicker when it happens. I was originally thinking it was the ecu getting too hot but recently just started doing it when it’s barely up to temp even. I checked all wires underneath the seat and all connections were solid. What would be the next move?? I appreciate the guidance!
