the next thing to check is compression and the injector on the offending cylinder. Since changing the ignition components changed nothing, it must be a fuel or compression related misfire.

I bought 6 Accel ACC-150117: 17 lbs. fuel injectors off of ebay and my cyl 1 misfire went away.

They sent 5 of the 150117's and one of something else but were quick to make it right. Still have the other one maybe I'll ebay it someday

I'm not a mechanic so it took me about 3 hours to install them.

good luck!!

Did you repalce 5 injectors or just the one that was missing?

Well i think i figured out the problem.....easy fix....ansoil PI fuel treatment...car doesnt miss any more and runs considerably better...Probably dirty injectors
