Some 1988-89 Regals assembled prior to the VIN breakpoint, indicated above, may exhibit a whistling noise coming from the rear of the vehicle when
the tank pressure control valve is venting to the carbon canister.
This noise condition is most apparent from outside the vehicle with the engine shut off after operation at higher ambient temperatures.
In diagnosing this condition, if the noise is eliminated by removal of the fuel tank filler cap, the vehicle may be repaired by installation of fuel tank
