Title: Spark Plug Electrode Erosion
Post by: Andy H on 31 May 2010, 22:03:12: I finally got round to fitting my new spark plugs today.

When I fitted new plugs to my last car I found that the spark gap on the old plugs was twice as big as that of the new plugs. The new plugs cured a misfire (on my old car) that I had wasted months trying to fix.

According to the service history they were changed at 78,000 miles and the car is approaching 125,000 now. 47,000 miles seems perfectly plausible looking at the state of them.

I changed cam belt & followers, oil, brakes, oil, air and pollen filters at 120,000 miles but it has taken me a while to get around to the plugs. All I need to do now is get the pliers I need to release the petrol filter ::)

Post by: Andy H on 31 May 2010, 22:26:50: I have a theory that a lot of the poor running problems that people have with their V6's are down to old spark plugs.

The plugs are such a pig to get to that people tend to put off changing them far too long.

You've neer changed the 6 plugs in a Smart Roadster (Coupe) then! :-? Half the rear end of the car needs to be removed to get to the lower three (2 plugs per pot ;))
