I am going to take it to the dealer for diagnostics, it could be something as simple as a cracked or corroded wire that I would not be able to track down. I cant figgure it out!

Thank you all for the info and insight!
Those are pretty good compression numbers... I'd be more inclined to think it's a wiring issue....

Good luck at the stealership!

I know about the stealership thing, but sometimes you just need to! It seems to do it more with a hard rain, I just noticed this today. Not to mention I had abdominal hernia surgery 2 weeks ago today LOL and it makes it hard to do what I have done so far!

Intake gaskets! Havent taken it to the dealership yet but I did some other testing and moisture appears to be getting by on the #7 and possibly the #5 cylinder intake gaskets! I noticed that it does it in the rain (hard rain or real humid conditions) and I got it dried out yesterday evening and it drove perfect! They used the original gaskets in the long block replacement (supposed to be reusable gaskets).

Does this make sense to anyone else, or am I way out in left field?

Well, you can get some brake parts cleaner and spray on the area while it's running, listen for a change. Yes, you could have a big vacuum leak, BUT it doesn't account for the injector code.
