So i bought a 99 civic ex with a b16a2 engine swap. I am having a lot of electrical problems and was wondering what i need to look for and steps in fixing it. All that i really know is that its not idleing right. It will run but i have to keep my foot on the gas otherwise it will die. Also the vtec wont kick in till about 6000rpm. I know part of the problem is there is a leak in injector #4 and when checking engine codes the iec and o2 sensor came up as there were problems. Also is there anything that i might have to wire in for the vtec? Any help is appreciated. Thankyou
