Twice when coming to a stop at a stop light, my toyota celica continued to idle at about 4000 rpm. i tried pulling the car mat toward the seat to be sure it wasn't interfering with the accelerator pedal. i also tried jiggling the accelerator pedal to be sure nothing was stuck. neither of these stopped the high rpm idle. each time the only thing that would reduce the rpm was to turn off the engine and restart it. the toyota has a manual transmission and the clutch was depressed each time during the high rpm idle. *tr
