2007, 5.3l, 61k is getting code PO121 and research shows it is the TPS. Is it a replaceable part or do I need the whole throttle body? Did not pass emissions due to this code. Would cleaning the throttle body solve it long enough to pass?
By the way, it runs great no issues of running rough or stalling.
Any help would be greatly appreciated.
