misfire code P0304

[Banshee]

I've been getting the misfire code P0304 (4th cyclinder misfire). I have no idea on where to start the trouble shooting. I've pulled the ELF and also the belt, so I'm naturally aspirated right now. Will see if the code return. In the mean time, got any suggestion?

So far, I've changed plugs to BKR7E, new performance wires, and battery.

Is it possible to remove the fuel rail and injectors without removing the supercharger?

You can get that for too rich or too lean. I got it (0301) on the 99 one day a few weeks back and it was a kinked tube from the manifold to the JRPC/SS. They were seeing the boost OK just a little slow with signal response. I found the 'partial' kink and fixed it and no problems since.
