2000 K2500 4x4 7.4L 454. Trouble code shows misfire on #4 cylinder. I have replaced the cap, rotor, wires, plugs, and fuel filter. Still a misfire. Hesitates during acceleration, no power at speed. Seems to run (ok) when cold, gets worse as engine comes to op temp. Could it be in the distributor? ECM? Coil?

Do you
have the same problem?
