what i suggested not knowing much of his car would be a vtec controller that he can program to turn vtec on at ??? and on the way down off at ???. ??? is whatever factory values were which i don't know for this engine.
huh? vtec is activated when the button is pressed??? sure is not NOS right? cos the way vtec kicks in is when it changes to highlift cam at a certain RPM, and I don't think u can push a button to switch to high lift cam like that.

well, it can be the wiring on the solenoid or the vtec solenoid itself is faulty. or if the previous owner (hopefully not) rewired everything wrongly. but its very strange to do so.

vtec controller is used to set on which RPM the vtec will kick in, but not at which RPM the vtec will turn off, cos its not the way how it works.

I still don't really get it about pushing the button thingy.
