With misfires, always start with:

-Spark plug reading
-fuel trim, to determine if a rich or lean condition is causing the misfire.

PERSONALLY, I would:

-Check compression
-If that's good, do the Valve adjustment
-check the 4 plugs, READ them, and make sure they are tight. Also make sure they are OEM Honda/NGK
-make sure there is no oil in the spark plug tubes

There are many things that can cause a misfire. I have cured many, on accident, just by doing this stuff during my routine Once Over on all my s2k customers.

Hey Bil,

If you are forced induction with the same problem, do you start at the same place?

I am running NGK plugs I step colder the 7173's.

Sometimes I get a cel, but it is only like once every month, but when I shift at higher RPM's it pops out of my exhaust.
