WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

There are no driveability concerns associated with the fuel rail pressure regulator unless a DTC is present. The most likely cause of this DTC is a sticking fuel rail pressure regulator.

If the fuel system pressure is actually too high, a fuel knock and smoke condition will exist.
