The fuel supply line to the rail has a quick disconnect, sometimes they're tricky, most of the time it comes right off as designed. Should be easy.

Sorry but I will not be able to reply for a while after this... will likely lose power for about a week with gustav. damn weather!

I hope you are doing well with gustav hitting your area. I again appreciate all your help on this issue

Ok, so here is what is new. Before swapping fuel injectors, I put a bottle of Lucas Fuel Injector cleaner. It runs great with a half bottle of the stuff. As soon as its done with the cleaner in the tank, the misfire comes back. But I can put half a bottle into the gas tank (about half full tank of gas ) and it will run and idle great with no rough idle at all, even at a traffic light! So what gives? A mechanic I know told me he thinks its a bad O2 sensor based off what I told him, he hasn't actually seen or test driven the vehicle. Any ideas on why the fuel injector cleaner clears up the misfire?

If you've already ruled out coil, plug and injector by cross swapping then the next step is to check signals to those components with a oscilloscope and compression test/leakdown test. If you have an 04 and up V8 it could be valvetronic related as well... if all else fails pay for professional diagnosis.
