New UK Owner! Question About Misfire

Hi Guys! :grin2:

Recently got a 2006 speed6 with 80,000 miles. Mostly stock (P.O had a venting dump valve, already ordered a turbosmart recirc replacement, this should fix my rich running)

I also have a P0303, misfire cylinder 3.

Who - 2006 Speed6 manual, with 80,000 miles
What - P0303, however I cannot feel the misfire
When - Upon receipt of car, and re-appeared with 50 miles of clearing code

I am going to swap the plug to cylinder 2 and the coil to cylinder 4 to see if it is one of those. I also have access to a fairly comprehensive OBD2 scanner, loaded with the mazda specific software - Is there a way I can use this to help diagnose the misfire?

Many Thanks,

Jack
