I have a 2002 MINI Cooper S, John Cooper Works with 97,000 miles. Lately, i get a miss when I am accelerating up from low RPMs (up to 3,000). The heavier the load on the engine (i.e. uphill, passengers) and the harder I push it the worse the miss is. This condition seems to be even worse when the engine is not up to temperature. I have also noticed a lot of 'soot' coming out of the tailpipe, as it accumulates on the boot.
