Hi everyone

Ive noticed recently my mini cooper s is feeling abit sluggish with pickup. Its due an oil service shortly but i doubt its that that is making such a huge difference.

Ive read of the ECU 'resetting itself' and learning how to drive (I do drive it slow traffic often) but i havent reset it for some time now.

Are there any other things i could check myself? I intend to replace/clean the air filter when i change the oil too.

Regards
