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.

I would have to say NO on the plug wires,you can start with checking the fuel pressure.You should be able to rent a fuel pressure gauge and adapter from a auto parts store.

1.connect adapter to shrader valve on the fuel rail
2.connect pressure gauge to adapter
3.start engine and allow it to reach a steady idle

What is the Fuel PSI it should be 30-45psi if its under 30psi you could have
fuel line leak
weak fuel pump
leaking injector

If its over 45psi you could have
a blocked or crushed fuel line
a bad fuel pressure regulator

If you had a scanner for your car you could check for codes
