I have a 1994 Ford Mustang Cobra and when at idle the seems like it is about to die and then it revs to stay on. And when accelerating and at cruising speeds the car seems to cutout and the rpm gauge jumps up and down. I have replanced spark plugs and wires.Put a new cole on. And replaced the Mass Air Flow sensor and TPS sensor the O2 sensors and the fuel filter and checked the fuel injectors. And also the egine and fuel pressure is all fine. And i dont have a check engine light on

You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
