hi im trying to chase down an issue in my 07 si and im alittle stumped. car is not hitting vtec. i found an oil leak at the spool valve and replaced the gasket for that and cleaned it all up. cleaned the mass air flow sensor as i was having an issue with that and that seems to be fixed but still not vtec. oil is full and clean and its not throwing any codes. my next attempt is gonna be too install the oil control valve off my parts car and see what that does. any advise would be great. thanks!
