A couple of times over the past couple of weeks, my Mini has idled really rough, almost to the point where it felt as if it would stall.

Here is a description of the circumstances
1. From a cold start (no problem starting), run the car 5-10minutes around town.
2. Pull to a stop. Mini seems to idle fine. Within 30sec, Mini start to idle rough and feels like it is going to die.
3. Press on gas pedal briefly. Mini revs up fine then idles correctly afterwards.

I need to put my code reader on it but not sure what to look for.

Appreciate any comments.

SOuld have added that my mini is a 2004 Cooper S with about 56k miles

 

I'd try cleaning the intake tract with seafoam might just be dirt/grime
