Flushing the throttle valve or upgrading the firmware in extreme situations entails drilling a hole in the throttle valve as a solution. Other Duratec and Duratec HE problems include tripping, vibrations, knocks, and noises that are caused by faulty components; see HERE for details about “Malfunctions”

This engine is one of the most difficult to repair among Duratec, and it’s best to go with a two-liter engine.
