the problem occurs more often after it rains or if the truck sits overnight on humid nights. while driving, the truck will start to buck and kick and if i am lucky enough the service engine soon light will come on. checking the error reveals the same error every time - p0300 random/multiple engine misfire. no kidding! the following have been changed, some more than twice: spark plugs, spark plug wires, distributor cap, rotor, magnetic pickup coil, ignition coil, fuel filter, fuel pump and egr valve gasket. before the actual cause of this error code is ever found and corrected the truck will more likely fail during a life threatening situation. this error code and the bucking of the truck has occurred since around third year of ownership (1999). *jb
