Missing Problem HELP!!!!!!!
I have a problem that I cannot solve. I have taken the truck to FORD and they cannot solve it either. The truck under normal driving misses and surges very bad. I have done the following: Plugs, plug wire, dist cap & rotor, complete induction clean (FORD Service), checked timing, FORD diagnostics. None of the previous attempts have fixed the problem. Could this be a throttle position sensor as it does seem to happen around the same RPM range?? Could an alternator cause this?? I have disconnected the EGR valve and the problem did not go away. HELP!!!!!!!!!!!
