My 97 Dodge Ram 1500 started pinging under acceleration two weeks ago.
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?

Check your fuel pressure it's probably low or an injector has gone bad, fuel pressure should be 44-54 psi for 5.2 l as you didn't put engine size down
