Question about 2006 Chevrolet Impala
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?
