- 1991-1994 Hercules ImpcoBuilt January 1991 to June 1994
What the defect is
The engine throttle plate shaft can become disconnected from the throttle lever assembly. The hex head locking screw between the throttle stop assembly and the throttle shaft can loosen. Also, the hex head pinch bolt between the throttle lever and the throttle plate shaft can loosen. The throttle return spring controls the throttle plate position through the throttle lever. If either screw loosens, the throttle return springs no longer control the throttle plate position.
What could happen
Unanticipated full throttle conditions can occur,resulting in a loss of throttle control and possible accident.
What gets fixed
THE THROTTLE BODY HAS BEEN REDESIGNED TO INCLUDE A SECONDARY RETURN SPRING ATTACHED DIRECTLY TO THE THROTTLE PLATE SHAFT. THROTTLE STOP ASSEMBLY AND SECONDARY RETURN SPRING LOCKING SCREWS WILL BE TORQUED TO SPECIFICATION AND TREATED WITH A THREAD SEALING COMPOUND SPECIFICALLY DESIGNED FOR THREAD LOCKING APPLICATIONS.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 1 July 1994.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.

Check your own vehicle
This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
