Default Engine misfiring at high RPM 2001 S2K

I have a stuttering in the engine at high RPM after VTEC. Usually between 7-9k. Not abrupt but a noticeable stuttering in acceleration. Definately not reving or accelerating smoothly or fluidly. Plugs look ok but have 20K miles on them, Any ideas? Thanks!

Check your oil level. VTEC uses oil pressure to come on.

Oil level is exactly between the L and H on stick.

Do a MAP Whack? It's free...

check air intake filter.

Take off the VTEC solenoid on the passenger side, check the little screen for particles/obstruction. While you're at it, check to see if it actually works.

Any CEL codes? Any pending? CEL on?

What plugs you have, stock? 20k is nothing to them, if you're stock.
