In rare instances, throttle sticking may occur on a few vehicles in very cold ambient temperatures after operating at steady speed or extended idle for a period of time. This may be due to ice build-up from moisture in the PCV gas on the throttle plate or throttle body.
Verify the condition is not caused by throttle body sludging, throttle cable binding, or interference between an improperly positioned floor mat and accelerator pedal. If no other conditions are identified, check for evidence of PCV system backflow. Refer to the following Service Procedure for details.
Inspect the inside of the clean air tube at the PCV closure hose connection for presence of moisture, oil, or oily stains. If evidence of PCV system backflow is found, replace the PCV system with the PCV Service Kit 1L3Z-6A603-AA. Refer to the Instruction Sheet within the PCV Service Kit for Service Procedure.
