Guys I have a 92 5.0 and the other day I crank up the car and let it warm up, take it for a joy ride and the car is spuddering when i give it gas. So i said must be a plug wire looked under and everything is tight. So next i went and got a new fuel filter and changed it. Same thing I didnt change the wires but I did pull all the plugs they look great what do yall thing.
