can a vacume leak cause vtec to not want to engage fully? I have a bad vac leak to my brake booster and i forced me to retard the timing like crazzy to compensate for the leak. This is a new ls/vtec swap and I have checked everything else I mean everything.

 

how can it not engage fully? it's on or off...

 

ok i mean it comes on then it goes off very quickly and i get code 22 vtec oil press switch i just put a new one in and its still fudged can it be the result of a very bad vacume leak
