Some 2004 F-Series Super Duty equipped with 5.4L or 6.8L engine and manual transmission, may exhibit a buck/jerk, surge, or hesitation.
Verify there are no diagnostic trouble codes (DTCs) using NGS. If DTCs are found follow normal PC/ED diagnostics. If no DTCs are found, or normal PC/ED diagnostics do not resolve DTCs, road test and monitor the VSS PID while the concern is occurring. If a VSS spike is observed, install a ferrite bead in Circuit 351 at the PCM connector using the following Service Procedure.
