Maybe you guys can help.. Misfiring 06 s40 t5

Alright... I have a thread over on swedespeed

http://forums.swedespeed.com/showthread.php?t=261473

We have an s40 t5 awd with 35k on it... And it's having a misfiring problem. 2 and 4 misfire on startup, sometimes. It also sometimes cranks but won't start but always starts on the 2nd try. It runs great otherwise.

I've replaced with oem parts...
Plugs (0.7 gap)
Coils
Fps
Cps
Drop tested the battery and had it checked at 3 different places, and its from 2013
Checked the fuel pressure, it's 60 at crank and 43 at idle. Freeze frames show the same and no other irregularities

I figured maybe somebody here might have some ideas.

I read in another forum that this could be possibly due to a bad camshaft sensor. In your case I wonder if it could be a fuel problem which is why it might take a few tries to get it started...

It ended up being messed up valves, the head is in a machine shop right now. Didn't see that one coming.
