Completed the L67-->L36 top swap and now I have a cylinder 2 misfire.

What was added:
Ported LIM
HVIII
L36 UIM
new gaskets
ported TB
Modded rails

Car ran fine with the gutted M90 case.

Here's what I have tried:
Different plug
different plug wire
switched coils

I'm going to switch injector 2 and 4 tomorrow

Anything else I should consider?
