    Good morning! This weekend cleaned my throttle body keeping it in place. Also cleaned my mass air sensor. Disconnected negative battery. Now when I start my truck it stays at high idle approx 1900 rpm. Any thoughts to help me resolve this. Thank you so much?????

    Drive it for 50-100 miles. Typically the RPM's will drop as the ECU relearns. It just takes some time.

    turn the key to run without the engine running. Slowly n smoothly push the gas pedal down to the floor and slowly let it back up (and by slowly i mean take 1 second per direction so not super slow), do this like 3 times then turn the truck off and pull the key out. Then start the truck, should be back to normal. That process will calibrate the throttle body to the ecu and help it figure out things quicker.
