I have a 99 grand am LE. I bought it used. Is there a way to turn off the check engine light so i could get my smog certificate. It passed however since the check engine light is on cant get the certificate. I know whats wrong with it but cuz i had to re wire it to get the fans working to prevent blown headgaskets and cool the engine. Now the computer dosnt recognise the wiring i did.
Dont have the service manual so somebody please help. Is there a way to do it without the scanner.
Thanks in advance.
