here's the deal. i have a 95 EX coupe, with a jdm vtec d16zc. Vtec has worked only a couple times since i've had the car. been driving it about 2 months now. and it's worked maybe 4-5 times out of at least 100 tries to have it kick in. only codes i'm throwing is 1-o2 sensor and 14-iacv. the car runs fine, all the wiring is fine, no loose or weak looking connections. just no vtec, oil level is fine....can anyone give any advice as to what may be the problem? any advice would be greatly appreciated.

 

get those codes fixed, the ecu runs in limp mode, so u dont blow **** up

 

The Vtec will not work unless you get rid of the 1
