Engine Performance problem
1998 Ford F150 V8 Two Wheel Drive Automatic
Truck seems to idle perfectly. Usually runs strong for about a mile, then it starts to vibrate at acceleration only. Then seems to cruise fine until I accelerate again. Replaced fuel filter, oil and filter, plugs, plug wires, tested the 2 coil packs, repaired (I think) leak in pcv hose - will check it again. Coded a misfire on cylinder #2. Tested resistance on fuel injector and the wiring harness is producing 12 13 volts. When I cleaned the wire harness that connects to that injector, the problem went away for about a month but now I can't seem to replicate that. Problem persists. Also checked fuel pressure. Could this be that pcv hose or might it be a problem with the cylinder itself?
have the same problem?
