Thanks for your help and support. Pulled the throttle body and cleaned it with throttle body solvent.Pulled the idle air motor out of throttle body and cleaned it good.Put it all back together.The car fired right up and no sevice engine light.Did a good test drive and all is well. no idle problems or reving up or surging. PS, there was a medium amount of black residue on the engine side of the throttle body and the throttle plate and the mechanism for the idle air motor, the cleaner worked good,Have a great day!
