on my b16 everything was just dandy working great. Now for some reason in 4th and 5th and sometimes third the vtec kicks off and comes back in. in forth it almost doesn't come on at all. my first thought was ign. timming. It seems like mabey the knock sensor it shutting it off. It sure better not be my gas because i just filled up with 93 at Shitgo. Is it possible the pressure swithch? and my computer is acting messed up too. the vtec is turning on at 4500 and the fuel cut is comming in at 7400. Did someone send me the wrong ECU? I thought it was the tach so i got a Auto meter tach and it is right on. is it possible that my tach signal is messed up. That would make sense why everything is a grand off. Does anybody know of a b16 trouble code chart? I'm not throwing anything now but it would be nice to know.
