These symptoms *could* be a WUR, aka Control Presure Regulator, but they could also be caused by a lot of other reasons. Has the car had a tune-up recently or ever? Worn ignition parts, spark plugs, wires, etc, can also cause hard cold start symptoms. You could also have a problem in the cold start system. These things have to be checked BEFORE you start throwing parts at it! There is no one thing that causes these symptoms. I like to review the service history of a car before attempting diagnosis. If a lot of parts were recently replaced one could be defective or improperly installed. Also what was the origional problem? This may not be in your case but if there was any recent work and now you have a problem then that work is suspect.
