My car had been sitting a couple days, because i was out of town, it didnt get real cold, dont even think past freezing, plus it was in the garage, i get home to today and start it up and it sounded pretty bad, almost a puttering type of sound and it took longer to start up, i was alittle nervous so i drove around a bit then started it back up at the house and it sounded a bit better, but still didnt seem normal. Is it normal to sound like this after sitting 2-3 days?? Do i have a bad something in my engine???
