Hello, When I start my Delorean after a week or so of not driving it, a lot of exhaust smoke comes out. It's not a bad looking smoke, just a lot of exhaust. Is this normal? Once the engine warms up or when I start to drive, it is fine. Also, when it is cold it tends to hesitate a bid in first. It will never stall or loose total power, just hesitate a bid when I give it some gas. Thanks for the help Erik Geerdink 4512
