hi, i have a 92 civic with a 1.6, and one of my fuel injector plugs dont work, so i swaped one off another civic it was a 92-95 civic i forget what one, but to change it do i just cut the wires and re wire it on? or is there a certain way to do it? also with only 3 injector plugs working does that cause my car to lose power?? and if i fix it it sould take off my cel..any help would be great..thank you.
