Redo the TPS. My situation of just experiencing light throttle on decel turned into car going WOT on the highway...had to pull the key and kill it. New rewire (longer wires provided in the kit so they aren't stretched) fixed the problem and then it came back after a couple of years. Replaced the sensor, harness and wires that time and it never came back.Im bringing this from the grave again. Having the same type of issue but it doesnt happen constantly. About every time I drive but not the whole time. Replace IAC and jiggling wires does nothing to the TPS and IAC.
