Help! My new DMC won't start

["jeff512tr" <cingular512@xxxx>]

Hello,
I have just recently purchased a late 1983 DeLorean (20022). The car 
only has 4000 miles on it and it's beautiful!
The car seemed to run well after being driven for a few minutes, but 
the cold idle surges up and down and the car is VERY, VERY sluggish 
for the first few miles whenever I drive it.
Yesterday I was doing some detailing on the car, but when I tried to 
start it to put it back in the garage, it wouldn't start. It turns 
over fine, but just keeps cranking.
Any suggestions for me? I would appreciate any help, as the car is 
now stuck in my driveway.
Thank you
Jeff
