Still Have a Miss
Ok so my car started to miss fire so I changed plugs and wires, AC Delco Gaped at .45 then and the wires are MSD 8.5s. It still was missing and I changed my opti and coil mew GM unit on the distributer and an O'Reillys unit on the coil. It is Still Missing on one F***ing cylender except every once in a while it will kick in on all 8 but then go back to 7. It never runs on all 8 more than a few minutes. So WTF could it be
Thanks

You're positive it's a spark issue and not an fuel injector? Also you should try taking off a valve cover and make sure valve train on that cylinder is functioning correctly and nothing is amiss. Also a compression test wouldnt be a bad idea.

try LIGHTLY tapping on the fuel injectors with a screw driver or something, that usually will get them to unstick aslong as there not too bad. Id also recommend the GM in tank fuel injector cleaner. Its a little more then an off the wall brand, but it works very well.
