Ok so i recently bought a 91 Crx Hf......at certain rpms it would pop and sputter so i narrowed that down to one of the plug wires missing the rubber part thats down in the valve cover.....replaced all the wires, plugs, cap, rotor, and Ignition coil. Now it throws out the CEL code 12? idk why it wasnt doing it before tho? where can i locate this in my rex any help would be appreciated
THANKS
