Your hard cold start is not the run-of-the-mill problem. When you start cold the accumulater is not "used" and it starts hot so don't start there or the check valve in the fuel pump. When cold the motor uses the cold start valve and associated components. I would look for trouble in the cold start system but it sounds like a control pressure regulater to me.(That's also used to enrich the mixture on start-up).Look over ALL of the vacuum hoses, a vacuum leak will wreck the idle especially when cold. On the subject of upgrades contact a Delorean vender for an upgrade kit consisting of some relays and circuit breakers. If you talk to them they will figure out what you have and what you need to order depending on what may or may not have already been changed. They will also be glad to help with your cold start problem and you will need them anyway to order the parts. You may also consider getting an extra oil filter and if it's been a long time or maybe you still have the origional ignition parts you will want to at least change the spark plugs and ignition wires.

When cold my car usually starts right away, but it will stall if I try to idle at a stop sign for the first minute or two of
