Got the P0121 code the other day and its real intermittent, but did some searching and wasnt sure if cleaning the throttle body and MAF will actually clear this code, or if I will need a new throttle body since the throttle position sensor is integral to the unit.
Also, anyone been able to drive or wait out the re-learn process that normall needs to be done with the GM scan tool? Heard that the truck could idle at 2,000 or higher.
thanks
