Dave I emailed you back from day one and even Sunday. Seen your email last night if I got yours - I sent another email and sent the original 2 back to you. Did you get them this time out. If not send me your phone # and times to call in a new email and I will get back to you that way. I have no idea why you can not get my emails. Sorry. John

Hi Guys -
As usual a good search of these forums has found my exact problem - down to the cylinder. Does anyone know the resolution to this issue?
Bonesmalon - did you ever get #6 to clean up? I've done all the same things including new plugs, wires, swapping coils, even pulled the plenum and swapped injectors as well as swapping ECM's between engines. Compression tests turn out within 1% across the entire suspect engine and going to do leakdown later today; but I'm very curious if this was resolved because if that turns out normal then I'm totally clueless - can't pull the proper RPM, still blacking out #6 plug and sounds very suspicious at idle.
Thank you all so much for any info on anyone whom knows what the solution was!

Thank you Bonesmalon! I'm confused on how your leakdown as well as compression were good if the head gasket was the culprit - but I will keep that in mind. There isn't likely any way to test that theory on mine w out just pulling the head, is there?
I'm honestly down to the exact place you were given all the items I've switched and tried. That or a bad / worn wire in the harness somewhere...
Thanks so much for the advice,
Jeremy

Bottom line is leakdown is better than compression check but not flawless
