Having a prob with my 07 Suburban
Check engine light come on and shows a code, P0121. I have cleared it several times and stays off for a short time then returns. I have not cleaned anything

throttle position sensor. take off the throttle body and give it a good cleaning as well as the sensor. should fix your problem.
