Ever since FIS-Control MMI gave me the option to have multiple lists, one of them has been to monitor misfires. I have assumed that the occasional misfire is normal, and after 6.5 years my total is now 200. However there were 3 on my last journey and I think they are getting more common so I'll get the plugs changed at the next service. But I was wondering if anyone else has checked their misfire counts?

BTW I was referring to the total count, not the misfires per 1000rpm.

Dippy when you change the plugs its perhaps also worth investing in a new set of plug caps and leads?? Over time these can break down and become less efficient. When the Japanese launched their first 4 cylinder engines they had metal plug caps so as soon as it rained the outer two cylinders started to er stop!!!!

I'll have to get this on my FIS!, Haven't actually done a miss fire count on mine. I changed my plugs for Iridiums at 42k miles.

They do say a tuned car will wear plugs more and reduce the normal service interval of 55k miles, but it does also depend if you use the extra power on a regular basis.

Been too busy keeping an eye on my low IATs after installing the extra heat exchange! They go down to 25 degrees now! Must get a little thread together on it! Not really been on here lately. :)
