Chaps

Any ideas- M20 2.5 when pushed misses for around half a second between 3.5 to 4k revs- same place every time?

Where to look?

Worse on cold/wet starts

Resurrecting this tread- clear misfire and hesitation for first 15 mins from cold start

when warmed up no misfire at all

Suggestions? I am going to change the plugs this weekend
