The limited axial clearance can cause the movement of thethrottle valve to be impeded, the valve is unable to close. This impedance wouldkeep the vehicle from decelerating at the usual rate after the gas pedal isreleased; this could cause unexpected maintenance of speed and an accident.

Summary
Insufficient axial clearance exists for throttle valve, shaft, and housing due to the different thermal expansion rates of the separate parts when vehicle reaches normal operating temperatures and ambient temperature is 40 degrees Fahrenheit or less.
Actions
Inspect and repair the vehicle by replacing throttle housing if insufficient axial clearance is found.
