Occasional Slight Misfire - Mazda 6 Forums : Mazda 6 / Mazda Atenza Forum

I'm writing from England. I have a 06 2 litre TS2. Mostly runs really well, but.... sometimes I get a hesitation or slight misfire when going uphill between 2000 and 3000 revs. Only happens when the car's hot - say after a long run at 70 mph, or maybe on a hot day. The dealer found a discoloured spark plug and replaced it. It's been better since, but I got the problem back on a hot day running round town. Next day, and ever since, it's been fine, even after a long run.

Any thoughts? Put up with it, or keep taking it back to the dealer?

Seems to be sorted now. May be due to loss of power when aircon is on (see thread elsewhere). Very happy with car at the moment.

Enjoying this little chat with myself!
