Right just got a new set of plugs, coils & lead on the renesis (one of the trailing coils failed) took her out for a blast & then return about 20 mins later, thought i would take the plugs out to see what they were like trailing plugs were fine but the leading were very darkened/sooty considering i had ony just put them in & went for the one run, is it normal for the leading plugs to be in such a different state t the trailing plugs? Thanks James.
no one able to help?
yes it can be,but depends if on cold start cycle alot of time too.

Carl
