Re: 99 escort cutting out
Idle Air Controller is most likely the cause of your rough idle, also check your timing belt (wouldn't hurt). Can't really check those things, 'cept for the throttle position sensor, and maybe (not sure) your mass air flow sensor. They should have an ohm reading. A Haynes manual can tell what ohms each is supposed to put out, and how to check the others. ($11 at AutoZone)
