I have posted this on here before and nothing helped and im sick of not having vtec!! Ok first off its a 90 integra 4 door and i put my b16 from my 91 civic hatch in it. The motor ran in the civic everything worked great!!! Now... I used the stock harness from the integra and ran the vtec wire, the pressure switch wire, the knock sensor wire and the second o2 sensor wire. But I used the stock manifold off the integra so it only has one o2 sensor (First problem)... I dont get vtec!!!! (second problem) I have gone through the wiring like 5 times now and still nothing. I have checked the vtec solenoid to see if it works and checked the screen. Both fine. Its a pw0 and I have NO codes and i even tried my friends ecu. it idles high (third problem) I think i might know what that is but it has 2 sensors on the firewall maybe someone could help me with that. Do i just T the two together or cap one of the sensors off? My idle screw is turned all the way in and it still idles at 1500 or so.. PLEASE CAN SOMEONE HELP ME?
