Question about 2001 Oldsmobile Alero
Clean the throttle body, idle air control motor, mass air flow sensor, and replace the air filter.

After doing the things listed by others (which is good advice), do check of oxygen sensor (usually installed in or near catalytic converter). BTW, the problem can also _be_ a bad catalytic converter.

First thing I would do is change the fuel filter ,then put some injector cleaner in the tank and also replace your CO censer
on the exhaust pipe before the catalytic convertor .

You need to replace your IAC (idle air control valve). The IAC, like it sounds, control the idle of your car. When they go bad they will cause the low idle and stalling. The IAC is located on the throttle body and is usually held on with a couple of screws. It is an easy relatively cheap fix that you can take care of by yourself. Let me know if you have any more questions. Thanks for rating my response and for using FixYa!

Good chance that the idle Air Control (IAC) valve is dirty with carbon and needs to be cleaned. You can clean it by cleaning the in side of the throttle body with Throttle body cleaner (follow the instructions on the can), you can pick up a can at any parts store like Auto Zone. Disconnect the air intake tube from the Throttle body and spray the cleaner throughout the throttle body, make sue your clean the throttle blade and IAC passage way. Once your done with cleaning the throttle body and IAC passage way, just make sure you spray enough through the IAC passage way to ensure you get the IAC cleaned also. Once everything is cleaned, put everything back together and turn the ignition to the run position for 30 seconds and then turn it off for 10 seconds and then start the car, this will reset the IAC and if there is lots of smoke coming from the tail pipe. That.s normal, it's just residual cleaner and carbon burning off and will take no more then 10 min. This should clear up the problem, but check the wire leads to the IAC on the side of the throttle body for any damages like corrosion and after cleaning the IAC problem is still there. The IAC will need to be replaced, but i don't think so, since you did not mentioned any check engine lights on. Good luck and keep me posted, be glad to know your car is running 100% again soon.
