Jeep Compass is blowing smoke from exhaust, occasional black smoke. This usually happens when car is accelarting. Have noticed when trying to go over 30mph the car judders and pumps out black smoke. When the car isn't being accelerated it runs perfect, however on occasion i have noticed white smoke.
