Your Idle Air Control Valve (IAC) has gone bad. Unfortunately the part isn't cheap. Most part store can get this for you. Definitely call around and get prices...shop around!

Do you have a check engine light on? First thing I would do is unplug the IAC motor when the engine is warm. If the idle speed doesn't change you have a vacuum leak or a bad IAC motor. If the idle speed goes down you might have a bad TPS or IAC

TO WHOM IT MAY CONCERN:
My car will not idle properly until after it is warmed up.(1995 Olds. Cutlass Supreme 3.4)
It wants to idle up and down between 1000 and and 2000 and will stall out if I don't keep it revved up at 2000 until it warms up.
Thank you and have a great day.

Can't turn the idle down


you have 2 idle settings. one is for cold and one is for after the engine has warmed up. So find the scew that goes to the warm engine idle. turn it down and your set. You might need a Chilton to find what you are looking for.

Warm up


The high idle is caused by the choke and the high idle on the carb. It is working normal and you do won't to warm up this motor before going. When it is warm and you hit the gas it activates the choke pull off to bring the idle to normal. Your mechanic is used to fuel injection that will control the fuel/air mix according to temp. I still let my injected cars warm up so the oil can thin a little. If you jump on the highway with cold thick oil it can all wind up in the to of the motor.
