I've tried n54 tech, Bimmerfest and now im coming here in hope of an answer..

So heres whats going on my high pressure pipe on my fuel rail pretty much broke because the injection valve bracket wasn't bolted down properly im guessing. So then I smelled all this gas and lost power instantly and had to tow the car home. When I popped the hood, my engine cover was broken, my pressure pipe was cracked in 2 and there was squirting gas. Had to wait a couple days for parts they arrived replaced everything. Now I have the high pressure pipe on and when the car is on, it sounds like its squirting out of the fuel rail. Causing a really rough idle past 3000 rpm which sucks.. Also my waterpump and thermostat need to be replaced (fans spinning like CRAZY) this was prior to the fuel incident. Help would really be appreciated at this point guys. THANKS !

Sounds like theres still a leak somewhere letting air in (and gas out), which would cause your misfire on high load. No smell around the car at all? did u test pressure at the fuel rail could be that your pump malfunctioned and blew your rail and is now not in its best condition causing that misfire at high load.
