So 2 issues.
The first is i just did a head swap to another y8 because my first y8 head only had 1 good valve cover bolt holding it on. 2 were broken in the head, 1 was striped and the other was stripped before i got it and tapped to a new size. But after i did the swap my vtec no longer kicks like it did before. idk what it could be, I've tried a few things but none have worked.

The second issue is whenever i kick my rpms up to about 1600-2000 it acts like it is 2 stepping but isn't. it will do it even when it is in gear. any ideas as to why I'm having these issues?

Ive tried getting a new ecu (p28), and made sure all the sensors are plugged in.

-Have you pulled the Vtec solenoid solenoid off the head and verified the screen is not plugged up? Tried swapping solenoids?

-What do you mean two stepping? Misfiring? Could be a number of things. Need more information. Any codes?

Valve Lash? Good oil pressure? Clean solenoid filter? Solenoid works?
