    What year MINI please?

    Any mods?

    Miles?

    Check the sparkplugs to see how they look?

    Any recent software updates?

    Sprint Booster installed?

    That should get us started and dare I sound like a broken record but if you had a Garage then we'd be able to just look and see speeding the diagnosis process.

    :cornut: Is it throwing any ECU P codes as that would perhaps give you the diagnosis?:Thumbsup:
