Check the cable from the gas pedal to the throttle position sensor and if thats intact then its more than likely the throttle position sensor has failed, I see four or five different brands available average price about $130 for the part
Accelerator cable could have come undone or loose check it \out oops some one already answered sorry Ditto Valleyautotech
have you had the timing belt replaced?
Totally off the wall answer...maybe Anonymous, July 31, 2010, 20:21 should go check their muffler bearings and blinker fluid ?
