Do you FEEL any misfire? Is there a drivability problem? An emissions test problem? If the answer to my 3 questions is no, then there is no problem…Drive on…

All of those parts you have replaced, few of them have anything to do with a random misfire…Ignition coil(s), EGR valves…are the more likely suspects…

Caddyman is right. Coils, wires and plugs. A friend had an intermittent misfire code and after all the normal stuff was tried, it turned out to be a leaky intake manifold.

Exactly what fault codes is it storing?
