    most likely that throttle body needs to be programed

    How do I program the throttle body? And another thing that is funny is if I take the air flow casing off and position the throttle plate with my hand the reduced power light will go off and it will stay running but when I let it go it will pop a few times and stall out. But when the reduced power light is off the engine will run fine.

    most likely would have to be done at a dealer, electronic throttlebodies need to be programmed to the ECM..

    When installing new throttle body or ECM, the throttle position has to be learned by the ECM. To do this, turn Ignition On, Engine Off, for 30 seconds .

    I had a crazy thought but it might be right. I had a different car a while back, and by accident Put some diesel. Fuel in it and reacted the same way. So my question is, do u think if somebody put something in the tank that is not combustible it would have this affect. I thought of this because when I sprayed the cold start in to the throttle and press the gas pedal it idled right then stalled. What do u think?
