Now you have to see why it is misfiring. Since you said you already did plugs, wires, cap and rotor then you have something else. Either bad fuel inj, bad compression on that one cyl, or possible you have some air leakage from a bad intake gasket. This is where it gets hard, because you need a scanner, a noid light, inj. Tester, and compression gauge to see why it is misfiring.
