OK.. Just replaced my plugs, wires, distributer etc etc...All the old plugs looked the same, tannish coating and the center electrode was rounded otherwise clean...Are these normal just worn out??? I've looked at some photos of different used plugs and think that mine were just worn....Also is there anyway to tell if my manifold is leaking. Just replaced the EM back to the tailpipe and was wondering what to look for if it's leakin? As always, Thanks <img src="/forums/images/graemlins/cheers.gif" alt="" />
