I would definitely wrap up my wires in some kind of plastic to keep it away from the elements. Then tie them to the frame with some platic cable straps. For your app., the plugs should be gapped around .030-.032. What type of fuel pump are you running? Have you checked/replaced your fuel filter? What about your injectors? What size? You also need to make sure your MAF is clean. Do go out and bang around on it...use some contact cleaner spray.
