Re: 97 jimmy with a 4.3 problems.
I can see that, but a quick test with an ohm meter will rule them out. They can run fine until they get hot, or good at low RPM then shitty at higher RPM. You said it bogs real bad at 3/4, does it feel like the tranny is slipping or bucking? Those are also signs of bad plugs or wires. Its amazing how simple things are sometimes, they just dont seem obvious.
I am going to swing in and check on it tomorrow after I drop my lil girl off at school.

Update I am almost 100% positive it is the fuel pump.I was told by the guy that was working on it that is was checked
but I told him I wanted to see it with my own eyes. The fuel pressure at WOT is dropping to 15-20psi.
