I have a 08 mini clubman, rough start when cold, 2 or 3 starts and runs perfect. I installed new fuel filter and pump, runs great but still rough start. Help????

 

I would check the plugs and coils, make sure they’re gapped right for your application.

i would also check the battery.

lastly if none of those options work, if you’re already running 93 octane I would add some fuel injector cleaner. Wayyy cheaper then getting it walnut blasted which I would do last if all else fails.
