I replaced the plugs, wires, coil, dist. Cap and rotor.
Recently it has started to bog down when going up hill and downshifting.
Today it severely lost power when accelerating and triggered the check engine light.
The codes come up as engine misfire, multiple cylinders.
At low or little load the truck still runs fine, only under heavy load.
All ignition systems check out fine.
Am I looking at a fuel pressure problem or possible fuel pump/filter being clogged?
have the same problem?
