So I’ve got the misfire narrowed down to spark... I changed the injectors(and their o-rings), fuel rail, injector harness, and the intake manifold(with all new gaskets)

The misfire stayed on 4...

I swapped the ignition module from the fiancé’s 2006 L61 powed car, and the misfire remained, but when I swapped over its entire ignition coil/module assembly, the misfire went away and the car ran great(actually with the ported manifold it has noticeably more power above, say, 2500 RPM)

I just did realize that the boots can be taken off of the coil cassette... I’m wondering, what if it’s just a faulty spark plug boot? If one of the two coils in the casette had failed, logic says that two cylinders would lose spark, not just one... when I get back to my car, I’ll swap boots from one coil group to the other and see if the misfire moves
