My little brothers car started acting funny today. he has a 2000 Oldsmobile Alero it has 169K miles. its the 6 cyl. for some reason when you sitting steal at a light or stop sing the rpms drops likes it trying to cut off and it has alittle jerk to it while its doing it, but the car drives fine no other problems only when you sitting still. what could be the problem??

 You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

ok Ima try that tomorrow. thanks

its the Idle Control Valve right?? I just price one just incase i need to buy.

ok Hammer Time. I did everything you said and it gave it some improvement but it didn't quite fix it. It doesn't do it everytime you stop, but it does it ever now and then, and i actually cleaned it twice. So do you think i need to go ahead and buy the IAC now?? also there wasn't a small home under the throttle plate, u pub my finger all through there, looked in it with a flash light and didn't see not one small hole.

The hole near the throttle plate leads to the IAC. Unless you get a healthy spray in there, none of it gets to the IAC. It may or may not help. If the IAC is bad and binding. it will still stall.
