We figured it out. Since the ignition system seemed to check out fine, I focused my attention to the fuel system. I had good fuel pressure to the rail so I decided to pull the injectors. All 8 of them ohmed out fine, and all the driver circuits in the harness worked fine with a noid light. I pulled all the injectors individually and put power to them using a connector from and old LS harness. With 12v to each only one didnt "click". #5 which happened to be the cylinder with the consistant miss and code. I went ahead and ordered a remanufactured injector from Rock Auto (bad idea). Got it, installed it, and got a huge plume of blue smoke out the drivers side exhaust. Turns out the "new" reman injector was stick open and gas washing the cylinder. Long story short I got a GM injector from a local dealer and $140 later she runs like a champ. No miss, no smoke and ready for its final tune and dyno run on Saturday. Ill post up some dyno numbers then. Thanks again guys for all the ideas, support and for sticking with me on this.
