Cold engine and smoke

[delorean502@xxxx]

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
