    I have the exact same problem in my 91 olds cutlass supreme. Sometimes it's fine, other times when I start the car the idol is reving. Anytime I apply the break when the idol is like this, the car stalls.

When the ac is on car idols normally once the ac is off car idols very roughly like it wants to stall at times this is only when the ac is off. thanks..


Idle speed is probably too low. Most cars with electronic engine management automatically increase the engine speed when idling to compensate for the extra load of the air con. Unfortunately, with this type of engine management, a lot of cars don't allow you to manually increase the engine idle speed. It has to be programmed in at a Dealers with the correct tuning equipment.

Very low idol feels like its going to stall what is the proper idol rate for this vehicle? Should I be replacing the fuel filter?


750-950 is whats called for,, (RPM) if it runs fine while holding the idle at a higher rate,, adjust the rate a bit higher ( changing of the filter is always a good idea )

Low idle and stall


check your idle air control valve(IAC) its probably dirty and are not able to move freely
the IAC valve controls the air mixture at idol speeds

Stalling


It sounds like all it needs is a good tune-up. I would check the spark plugs, spark plug wires, air filter and fuel filter.
