Problem Starting
 

I turned the key over and the car fired up for a few sec and them died. I turn the key over again, and it fires up but the RPMs are real low. After a few sec the RPMs are normal and the car runs fine. The car has not done it since.

What was the temperature outside when you this happened?

It sounds like a vacuum leak problem I had recently with another car. When it was very cold outside, it would die until I let it warm up.
