Throttle Body: All Technical Service Bulletins
Recall 92V131000: Loose Venturi Tube

The venturi tube located in the throttle valve housing can become loose and fall against the throttle plate. The venturi tube can partially block the throttle
plate and prevent it from returning to its full idle position, resulting in unwanted engine speed when the vehicle is placed in a forward or reverse gear.

Replace the press-fit venturi tube with a thread type tube.

System: Fuel: Throttle valve housing.

Vehicle description: Passenger cars with 16 valve engines and california emission control systems.
