Question VTEC ?

Ok I just instaled a JDM exhaust manifold on my car and when I hit VTEC it seems to go into it out of and back into it again but only when im at about half throtle. It doesnt do it in full throtle. Any ideas?

vtec is RPM controlled as well as throttle postion. more then likely if u are not at full throttle vtec will not crossover..

yea...low oil and/or very dirty oil could cause this, or the screen on the vtec selenoid could be partialy clogged with junk.

Why are you driving at that high of rpm's at only half throttle? I myself know nothing about VTEC seeing as how ive owned a car with it for only 2 days...But mine seems to only engage at full throttle.
