Miss Fire

[josh92ranger]

I've changed the plugs, wires, cap, rotor, and the coil along with the fuel filter. I still have the miss and it is progressively getting worse. i ran seafoam through the intake and the tank and it had gotten slightly better but then it just went back to worse. any ideas that could help me out and possibly fix my miss?

do a compression test. i had a missfire and it wasnt the plugs or wires. a rod broke and the cylinder went dead.
