Swaped in a b16 into my 91 si, used hasport sub wiring harness, hasport says that the A8 plug was supposed to be free but it wasnt so we took it out and plugged in the vtec solenoid anyway.. we got the other wires pluged in and we start it up and it runs but its slow and vtec doesnt kick in, we also get a code 6, we are gonna try a new coolent temp. sensor and see if that works...any suggesting would be helpfull, thanks
