Day in and out those of us that help based on experience etc, we shake our heads at some of you guys.
You post that you get a code, and most times....you don't bother to research it. Pull your fingers out of your mouth or wherever you got them stuck and put them back on the keyboard. Type "google" and then in the search area "GM DTC PXXXX" with XXXX being the code.
You may be amazed at how the internet has information to help out. Then post up your problem being informed and the advanced diagnosis can being.
Thank you...I'm here all week.![]()
