Here are some images that might help to assist you, and let me know if you require any further assistance.
Adjust the curb idle with the engine warmed up and the choke off.
The air/fuel mixture screws should be adjusted with the engine warmed up and at normal idle speed, then turn each air/fuel mixture screw in one at a time until the engine just begins to mis-fire, then back the air/fuel mixture screw out 1-1/2 to 2 turns out a half a turn at a time until the engine idle is the smoothest. (your vehicle might have restrictor caps over the air/fuel mixture screws to limit the amount of adjustment)

To adjust the vacuum tension pull on the choke pull-off:
Adjust the fast idle screw to the proper RPM with the engine cold and the choke on.
Testimonial: "Thank you so much, where were you 2 months ago. lol. Do you maybe know anything about olds 3.8 engines?"
What did you require about your Olds 3.8?
If that Olds 3.8 is fuel injected or has a mixture controlled carburetor then it sounds like it might be the CTS (Coolant Temperature Sensor) for the computer and not the temperature sending unit for the temperature gauge/light. Most Oldsmobile engines usually have a sensitive cooling temperature circuit that the computer uses, and when the CTS gets out of range on some Oldsmobile engines they will not even start.

Thank you so much. It is a Motorcroft, and all the adjustments screws on the carburator would be great.
When car is cold it starts good, runs about 30 seconds and dies. then starts again easily, sometimes it will do this 2-3 times. Then runs rough till it levels out and runs good. It has a 3.8L engine. Please help confused. Thank you.
