I own a 04 MCS, and at stops say red light my idle will be at 1,000 or 700 then it goes low and the car hesitates to stay on then it shuts off even with the clutch in? I have tested to see what causes it and with the A/C on give it about 15 seconds it stalls but with it off it's fine. it's very strange but sometimes the car wont start until the third turn of the key I don't know if it would also be that i drive the car fast and shift at 5,000 and speed? mini's are so fun and it's my first car still under warranty and due for service in 700 miles. also if i put a supercharger pulley will i still have the warranty?

 

You need to have the fuel injection idle setting adjusted. This should be a free (warranty) item at the dealer.

Regarding the s/c reduction pulley, ask the dealer how mod-friendly they are.

 

oh ok!!! thanks for the info
