Hi all - I'm getting a hard engine misfire on my '05 JCW "S". It occurs when the car is warmed up, but the weather is on the cool/damp side. The only repeatable circumstances are at light acceleration at about 2200 RPM in 6th gear, but it sort of randomly appears in the other gears as well, always under light to moderate acceleration. The car has about 65K miles, just recently had an oxygen sensor replaced, otherwise runs great. Any ideas??? Thanks, Jim
