Running on 1&2, 3&4 not. Have checked injectors and replaced one that was not completly closing(#4),all injectors spraying.Checked spark (#3) weak plug had 125000 ohms resistance,replaced all.Coils between 5000 & 6000 ohms (1-4)(2-3),no short to cover.Multi spark not as bright as I think maybe it should be but all equal.No unusual noise,power steering pump turning,exhaust manifold 1&2 heats up,3&4 doesn't (first clue) plugs 3&4 very little soot,cylinder end of plug housing/ground staying silver, little discolorization on electrode(2nd Clue).It doesn't seem to shake quite as bad but still scratching my head.Whats next?
