What could be the cause of 96 duratec engine surge?

Answer by  neielg (311)

Probably a faulty mass air flow sensor. Just lightly tap the intake pipe with it running and if it changes the idle up or down, that's most likely your culprit. Double check the connections before you buy the spare. It must be clean and tight. You may also have a vacuum leak on the intake somewhere.
