P2176=Throttle Actuator Control System - Idle Position Not Learned
Did you use all you old sensors,or is some of them from the new engine,I would swap out the IAC sensor or check for wires not hooked up.
If it can't relearn to idle the Idle air control might be different then your old one,but its not registering with the computer
2006 chevy impala LT 3.5 V6. DTC P2135 and P2176. Engine power reduced has been happening intermitently. Shut the car off, wait a minute and restart. Starts and runs, engine light stays on and then goes off after sitting for a while. Paid chevy for a diagnostic and also to clean throttle body and reprogram. Was told if it continued happening I would need a new throttle body. Engine power reduced happened today, just one day after having chevy clean throttle body. Is replacing the throttle body the only fix?
I am about to replace the throttle body on my 06, but not sure if I need to relearn the computer to the new part..anyone know
Our 2006 impala has the exact problems. Did replacing the throttle body fix the problem? Hate to pay $500 for the repair if it doesn't work, but need to get the car going and reliable again! thanks for any help.
my car is doing the same thing, did replacing the throttle body help. I was told that is what i need to do! Thanks
