So peoples...im extremely new to the forum so if im doing this totally wrong please tell me but i have a issue that i cannot resolve an its killing me.

so in my hatch ive got a 98 gsr an when it revs to 5000+ rpms an fires vtec it wants to studder. So ive replaced the distributor ( which had cut wires to jump from obd1 to obd2 ) an it Really improved the issue yet it DID NOT FIX IT. So from there ive checked oil level, sending unit, an changed the top of the solenoid out. Still has A Studder issue Around Vtec. Now from idle to 5000 it runs PERFECT. I decided to completely disconnect the vtec solenoid an now from idle to rev limit it runs perfect yet i still want to be POSITIVE that a new vtec solenoid will resolve my issue before i buy a new one. So if anyone has any insight what so ever i will be glad to hear your opinions.
