Could it be injectors or trans

Injectors... get someone to do a Buzz test when engine is cold. Old oil when cold will cause misfires...until the engine warms the oil, then the injector will fire normally. Google Cold Start issues.

Plug your block heater in, and if it runs normally after heating up an hour, thats a good sign the injectors need rebuilt.

I'd almost bet its the #8 injector...

So today I got a new injector and replaced the one that was leaking. I pressured up the oil rails again and the new injector was leaking air little, not gushing out like the old one was but could still hear a leak from the oil return. There were also maybe three our four more injectors leaking also. Maybe a little air coming out of the oil return holes are normal?
I have about had enough of chasing down leaks, I'm just going to put it all back together tomorrow and hope for the best.
