Car idles fine and revs perfectly while in park or neutral, but in reverse with one foot on the brake pedal and the other slightly pressing on the gas pedal, I get a thumping noise in the engine bay for a split second and then the engine revs normally. This problem continues until the car reaches normal operating temperature. This only happens while the car is in reverse. It almost like a complete loss of power for a split second and then the engine will rev normally.
