do I need to change entire throttle body to replace idle air control valve?
Auto repair shop tells me they need to replace entire throttle body because the idle air control is programmed to match
If you have the electronic gas pedal then it looks like it is sold as one complete piece.
Not cheap either.
Don't know about gas pedal but it is gonna be about $600 bucks. The Idle sensor is mounted with two screws on side of throttle body but mechanic says its programed together with throttle body
If you don't have a mechanical throttle cable the gas pedal feeds your input to the PCM. The computer then operates the throttle blade. The IAC is part of the unit. I don't know about programmed to match. The manual just specifies that the new assembly must go through a re-learn procedure after installation. Looks like the assembly is 288 on rockauto so you can be certain that GM charges more and prob at least 2 hrs labour.
