We just swapped the fuse box on our 02 Turbo S due to a melted fuse, car was running fine prior. After swapping the fuse box with a new unit the car gave several errors related to the mass air flow sensor, turbo and an ABS warning light. I cleared the codes thinking it was just a computer glitch from swapping the fuse box and restarted the car. The lights stayed off but now the car runs like absolute garbage, shutting off at idle and bucking on acceleration almost like having a bad transmission. Is there some sort of relearning process for the ECU?
