There is a hose going from your air intake to the top of your cylinder head. Try removing the hose all together and than start the car. If the car start and idles normally or a little faster than it should you know you need a new valve. $12. Try that it happened to my car a few months ago. Same symptoms. If not you may be having some trouble with you head gasket. Spitting oil back on your plugs. Are your plugs oiled up or do they have a clean burn?

Pull the engine coolant temperture sensor and examine it for any sign of cracking. Very common on saturns.

Replacing certainly answers it, but You would be able to see a crack. Anyways,

Do you know what codes are listed in the computer?

IF not, the next area I would go to is to clean the IAC motor and EGR valve. Not sure if you replace the IAC motor as you referenced " air control senser".

Codes, if any, would be beneficial to know.

Did you replace the correct sensor. There are 2 coolant temp sensors on your model. One feeds info to the gauge, and one feeds info to the computer. You need to change the one for the computer. The gauge sensor is visible easily. The computer sensor is below that one and slightly to the rear.

Also, make sure you get a temp sensor with a brass tip and I would suggest getting it only from the dealer, as these things were suggested to me before I replaced my ECTS.
