Cylinder 2 Misfire

Cylinder 2 Misfire
I have a 2005 R53 has a misfire code for cylinder 2 and a misfire code for cylinder 2 low fuel. I have changed the plugs and these codes still come back. The ECU has a snapshot of the misfire at idle possibly a cold start. Any suggestions I was thinking new injectors...???

Check the vacuum source from the intake manifold to the bottom of the fuel pressure regulator, they are not fastened on and only slip over a small barb.
Plugs torqued properly? 25 ft lbs.
Try switching wires between 1 & 2 and see if the misfire follows the wire.
Compression numbers?
Injectors don't fail often, so I wouldn't jump to the conclusion of spending money on new injectors.

So, P0302 and what's the P code for your other issue, P0264? Any other symptoms? Check the wires and coil pack for any visible damage/corrosion. Yes, the injectors aren't too common, but have seen a few clogged before. A good NAM thread here on the misfire with some suggestions.
