    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?

    Just to rule it out...compression test and a leak down test...

    Ummm, seafoam?

    Sticky valve?

    I had that issue...it was a good, fun time.

    Injector, ICM and compression test is where i'd start.
