the throttle postion sensor is ok so the dealer put in a brake switch. still having the same 2-300 rpm surging above 50mph. anyone have a clue on what might be next? the dealer obviously doesn't have a clue. trans temp sensor? does anyone know how to rig up a bill kondolay mystery switch for trouble shooting this issue. i would guess one needs to first figure out if it is an electrical or hydraulic issue. thanks. scott.
