Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Driving on highway. The vehicle started racing. Could not stop. Put in nuetral,engine racing. Shut engine . Later found that the hook from servo had rusted and broken off and the bar attached to the throttle had gotten stuck in the throttle. This hook should not be of a material that can rust & break off like that. Also I have looked into the service manual & there is no mention of service to that part atall.why will the mechanic even look at that part if there is no mention for maintenance to that part. …”
