Hi All im looking for advice to get an 03 mini cooper s running properly I just got this car and it falls flat on its face if it is on an incline and trying to pull out . I have use full throttle to move just a little bit on an incline . This car has a 19% reduction pulley and I just replaced spark plugs and the map sensor . its like the car has no power to even move itself below 3k rpms and then it will sputter and sometimes misfire or sometimes it will take off and go when wot but the power cuts off right at 5000 rpm . Im new this is my first mini someone please help me ! Thanks !
