1995 4.3 #6 misfire
 

Have a 1995 4.3 blazer with CPI, beginning to think it is cursed..
Been nothing but a money pit since day one..
But now, have a problem that can't pinpoint and looking for any suggestions as to what it may be.
#6 misfire at idle and under acceleration
Scanner is giving p0306 code, which was already obvious as it is a dead cylinder
Have replaced plugs, wires, coil, distributor, ecm, knock sensors,
Compression seems fine
Took #6 wire off to check for spark and its showing a weak spark, have swapped wires from neighboring cylinders and even other plugs, still the same..
I know the CPI seems to be a usual culprit with misfires and also the egr valve, but my problem seems to be on the ignition side, but i cannot think of what else could cause just one cylinder to have a weak spark, have replaced everything i can think of...
Any ideas would be appreciated before i go melt this hunk of junk down..
Thanks

No idea, it's got an appointment with the local chevy dealership. Don't have the time to piss with it anymore. Will update on what problem is, if they can even figure it out! haha
