Hi gents, I have a 2000 Ford F250 SD 4x4 with 5.4l. I have a misfire and I have replaced the coils, cam position sensor, and the injectors but the problem still persists. Was thinking of changing the fuel pump but before I get into that just wanted to see what some of the experts have to say. Thanks

 

Is it one cylinder or multiple? Check the plugs to the coil I have multiple crown Vic's with the same problem and most of the time it's the coil or the plug to the coil
