OK, im running with an lsvtec and it has ZERO problems going into vtec, but where its problem lies is coming off of vtec after im done driving it in vtec. I can tell it sticks because i hear the lower rpms sputter and idle horribly, and the valves all sound like they're still opening extra wide. A few seconds later, itll throw my CEL. I can turn the car off and as soon as i restart it, all returns back to normal.

What could this be, do i need to replace the vtec solenoid plunger?? Or could it be an electrical thing, like i need to ground my oil pressure switch better? I have it grounded on the VC right now... lmk.
