when engine braking (especially down a hill). My mini stalls when i push the clutch in every now and then. the revs drop quite low and sometimes stalls/sometimes picks itself back up. It does this mostly in 3rd and 2nd, I dont engine brake in 1st so I dont know about that. Ive not checked the plugs etc yet for colour to see if its fuel related. any ideas what it might be?

Very first thing I would check are the elbow ends of the vacuum capilary lines, the most likely ones being those at the back of the inlet manifold. These crack and split alowing air in and causing the stepper to close off the throttle to compensate. Replace them with the rubber type http://www.minispare....aspx?pid=36449 Index the throttle cable as well.
On over run the ECU cuts the fuel above about 1500rpm and then progresively brings it back on below this. If the trottle cable has not been indexed correctly or adjusted to try and correct idle speed, with the air leaks above, the stepper motor may be in the wrong position causing this symptom. If the idle speed screw has been altered unnescisaraly, the only way to set idle air is with a diagnostic.
See how you get on

new bit of info!
squeeling go's away now the temperature has gone up a bit.
and it was happening between 4000rpm and 4500rpm and only when accellerating as hard as it will go. as the day got warmer it got less and less.
