hi all, we had some snow yesterday and it was minus temperatures most of the weekend. the car was running fine and starting fine friday, but when i went to start this morning it struggled to fire. the starter turns fine, so i dont think its the battery, it just sounded like it was running on two cylinders, then chugged for about ten seconds, then kicked in and started running if not a little chuggy when it was cold. is there anything common i should be looking at? its a 1.6 petrol, does it have coilpacks or a dizzy cap?
