2001 Pontiac Bonevillehi I’m trying to see what would be causing this to happen. I start it up, it runs at correct idle till it warms up and then it wants to idle down to the point it wants to stall. I have my own theories but I need a second opinion. Thank you.

If there are no check engine light codes I would think cleaning the throttle body and putting in a new air filter would fix you right up. Clean the throat and edges of the butterfly in the throttle body. Use starting fluid and spray it on a rag and wipe. DO NOT spray into throttle body.
