I have a 2005 Pontiac Grand Prix GT that has given me 3 different problem codes and I cannot find the correct manual to fix the issue and cannot locate the parts on the car to know what to replace. Can you please help? The problem codes are P0449, P1125 & P2138. I also believe P1125 & 2138 may be the same issue. Is that right or possible?
Please help : ) & Thank you

449 is an evap issue. you need a smoke machine, scan tool and volt meter to determine the failure.

the other 2 are fly by wire. you need to have the throttle body and pedal sensor monitored by a scan tool to determine the failure.

parts for either system are readily available anywhere
