Havn't tried... Worried about causing damage... Sure I am OK to do this?

It is impossible to get to insitu!! It is my Fiencee's Mini and mine has
been taking rather more attention recently... I also think the problem has
got worse over the past few months. It was just noticable when driving...
moving off the line it would be difficult to stop it bogging down if you
wanted to get away quickly. Now I can almost get it to stall by blipping
the throttle repeatedly.

Thanx,
