    P2176- Minimum throttle position not learned.

    Try the relearn procedure again, listed here.

    Hmmm. That seems very odd. Maybe try relearning it and clearing the "pending" code with the scanner. If that doesn't work, try starting it a couple of times as it is possible that the ECM may need to read a couple consecutive positive instances before it will clear itself. I've seen similar situations with other trouble codes.

    If that doesn't work, I'm out of ideas man. I guess disconnect the battery for a while and see what happens?
