skinnyman9000 0 Posted May 19, 2010 Recently the C has developed a slight misfire, sounds like its on race cams, but its not. I had a gander around the engine bay and noticed that the ends of one of the HT leads (where it attaches to the spark plug) had some white powder around it. Is it likely that the spark plug is knackered, and that this is causing the misfire? And that a simple spark plug replacement (on all 4 obvs) would solve the issue?

Wullie 1 Posted May 19, 2010 Could just be a bit of corrosion. Try giving the lead ends and plug tops a good clean up ans see what occurs. Quote Share this post Link to post Share on other sites
