next i was thinking bad thoughts and thought i had low oil pressure.
hooked a gauge up and it has 25 psi hot at idle and 75 psi hot wide open throttle

Did you not read the 1st post by OP?

I took the girdle back off to make sure none of the pins for the rockers fell out (for the secondary vtec rockers) and all of the rocker pns were snug as a bug

then i thought i could be the wiring or the vtec solenoid (tested the sloeniod on my buddys car, works) wiring is fine too aswell as my ecu. (running neptune)

Again....did you even read the VERY 1ST POST?
