ok i just got a 2000 civic ex vtec dizzy and wired it to fit my obd2a harness unlike before it starts right up and runs perfect but....there is one wire on the obd2b harness wich is gray that i cant find what slot to put in and ofcourse 2 wires both blue shades that arent plugged up. it starts and runs but wont go over 3.5k rev still. i have a p28 ecu should i just unplug the ckp sensor and reset cause i know what code its throwin. but i know that virgin p28's are n/a to the ckp. so tell me do i unplug it and reset or wire it somehow?
