I have absolutely no idea how vtec works. From what I've read, it's got a lot to do with oil? Not losing any oil or anything. The aircon is basically always on though. When I go in to service it, I'll put it up on the hoist and have a look over everything. Anyone know anything about the solinoid or whatever for vtec? Apparently I should be checking that too. Vtec is totally weird to me, after only owning turbo's.
