Having problems with your 2003 Mini Cooper ?

Engine runing rough on start up

\015 On cold days my Mini S stumbles like it is flooded and does not like to run smooth. Sometimes it clears by giving it some gas with the shifter in neutral. Other times this happens even after driving a number of miles. This car is driven in Minnesota and this usually happens when the temps are close to or below O degrees F. The car has been taken to a dealer however they do not appear to have a fix for this condition. They reported ice after the butterfly in the throttle body.\015 Posted / edited by AnonymousUser on : 16-04-2018
