My friend just bought a used 2002 Pontiac Grand Prix. He has already spend a small fortune fixing the car up and now the engine light is constantly on. He was told that is has something to do with the PCM. Also, when he first bought it, the digital light on the winshield was working and now that is out too. Is there something He can do to fix this PCM and have the engine light stop coming on??
Problem with the PCM- 2002 Pontiac Grand Prix why is the engine light on?
