#1 of 2 Misfire Cylinder 3 by honieroy

Ok, this has been my nightmare. The engine is a 350, bored over. In the last two years, I have been dealing with misfire issues. I have replaced the cats twice, distributor, spark plugs and wires with heat shields, and the spider injector. I am now back once again at square one with a cylinder 3 misfire. I can't afford to keep having it diagnosed to not ever find the problem....Any suggestions? I am completely frustrated.

Could it be a mechanical problem, instead of electrical........intake manifold gasket? head gasket? Not sure how the computer would know it was cyl 3, but pulling at straws.
