So my brother has a 02 Cadillac ext and wants to scrap it because he keeps getting reduced engine power and a 5v reference code for the dbw throttle body. I think it's the dbw throttle body that has a fault or something so I was thinking of doing a segment swap with a dbc tune to fix the issue. Or if anybody knows what could be the issue the help would be appreciated, someone mentioned a abs sensor that could be throwing the car into reduced engine power.but idk. The car drives perfect besides the reduced engine power every now and then.
