The car starts fine when it is warm but if the temp. drops below 45 degrees the car takes a while to start. I thought it was the battery so I installed a new one--didn't fix the problem. When the car does start, I have to rev the engine for about thirty seconds or else the car will stall. While waiting for the car to start, there is a lot of gray exhaust which I take to be excess fuel being burned off. Any suggestions? I took the car in last year with the same problem and the mechanic looked at it for a day and couldn't figure out what was wrong.

The car is old enough to possibly have some deposits on the injectors.
I recommend any brand of cleaner that lists NAPTHA on the label, it is strong stuff so don't get it on the paint. Just put it in the gas tank before you fill up to be certain it gets well stirred.
Be certain your engine oil is the thinnest weight recommended for your engine. I use 5W30 on all my cars for winter driving and they do start better with it.
And test that your charging system is putting out enough voltage to keep the battery fully charged.

Sounds like a bad temperature sensor. What I recommend is to leave the car at the shop Sunday evening for drop off and leave keys for the shop manager to park the car and pull the keys so that the car can be (when temp is below 45) started only by him to confirm what is happening to you. If this occurs, he can have his technician do the repair and again park and lock the car for recheck on Tuesday, Wednesday, Thursday and Friday when the car is to be started in the AM with the temp below 45. The 2 of you are to touch base on this problem.

coolant temp sensor or connector is defective
Its located just underneath the radiator fill cap that is mounted on your v6 engine. its the 2 wire sensor not the single wire sensor. the single wire sensor is for your gauge on the dash. the 2 wire one is for the engine controller and is called a CTS (coolant temperature sensor)
