On certain vehicles, the accelerator pedal may stick and cause the engine not to return to idle when the pedal is released. When applying pressure to the accelerator pedal, the no. 2 heater duct may hook the pedal linkage which will reduce pedal travel and not allow the pedal to return to the idle position. Correction: No. 2 heater duct will be relocated and secured away from the accelerator pedal linkage.
