I have a 94 mustang gt, It has the 5.0 H.O.... It seems I have been plagued with the famous rough idle, as well as a miss as throttle is increased. I have read many similar instances. And tried alot of them...yet this remains to haunt me. I have a new mass air flow sensor,
plugs,wires, cap/rotor, IAC, and TPS. Vacum guage indicates green. as well as the spray test for leaks also turned up nothing. sometimes at WOT, it backfires.... Is there another avenue for me to follow?
it almost sounds like the timing is off on the car. there is a modul u can remove then check and adjust your timing. when it is adjusted to the i think 10 degrees u shut off the car and plug it back in.
I Just got it fixxed.... thats to some long reading out here on this forum, and alot of very knowledable people. It turned out to be the distributer pickup. I cleaned it with brake cleaner as discribed in anothers post. And the darn thing flies....:shiny: thanks again everyone.
