I have a 1999 Pontiac Grand Prix and the engine light is on. Although it appears not to hamper performance, I went and bought a OBD II Tester.
I now have the codes in question, were can I go to find out what is causing these problems.
Also since this is a used car, I thought of clearing the codes and starting new, is this possible.
Any info on this matter will be appreciated.
Thanks.
Jeff
