Evo seems to be running on 3 cylinders. It sounds like a Subaru.
I have replaced the cam angle sensor.
I have checked spark. It's getting spark. Put in new spark plugs and tried oem coil on plugs (I'm on spoolin up)
What else should I check here? I don't see any boost leak.....

pull each coil plug and see if the misfire gets worse, if it doenst that's the dead cylinder-- check the wiring and replace the coil--- I have had that happen twice in the last 4 years on cop.

Well it seems like cylinder one has zero compression. All others are good and timing is good. It's getting spark and fuel.
I popped off the valve cover and head looks OK. What could have gone wrong here?
I wanna get some opinions before I start tearing apart the head

Put a little air in that cylinder and see where it goes.

A Leak Down test for that cylinder is in order.

Did you check to see if you're gettig fuel to the cylinder. May have a bad fuel injector.

If No compression in cylinder one means zero psi then you have a stuck open or bent valve or a hole in your piston.
