Hey Folks
My check engine light has been randomly coming on & off, and now its been on for 2 days. OnStar gave me a code reading of P0121. Truck is running smoothe, nothing out of the norm, except the light. They said the code gives no other readings or warnings but to take it in to get looked at and that it has to do with the Throttle Body. Does anyone have any further input or suggestions/advice? I recently moved to another state and have no time off to take it to a dealer. Is there a chance I can fix this myself? Any help is appreciated.
Thanks
