Title says it. 94, 5.0, won't run right. Seems like it's misfiring, pretty much no power. Warrantied out distributor, tried a few different caps, two sets of wires, no vacuum leaks I can find, another set of plugs. Any ideas? Going to double check a few things when I get home tonight, see if I can see any arcing or anything at night, since I'm pretty sure it's ignition from how it sounds. Sounds the same as when I've lost a plug wire before.
