I have a 92 F-250 with a 460 motor. I started to notice that the tach would drop to 450 and then kick back up. Then while driving it started to miss. It acted like it didnt have the balls to go then it would kick in for a second or two then start doing the same thing. So i have changed the idel air control , throttle postition sensor, map sensor, fuel pressure regulator, ignition module and nothing it still is doing it and it seems t be getting worse. Its a 5 speed so i dont think the tranny could be causeing a problem. Please any help would be great replacing things are getting expensive. Also i have had the codes read and its clear.
