I would start with throttle body air flow. Inspect/replace the engine air filter. Inspect the throttle body and vacuum lines replacing any cracked lines and clean the throttle body.





I think it’s less likely that your alternator is failing at low rpm but you may want to confirm 13.3V or higher at the battery connections when idling.

Have you tried scanning for codes? Could be a vacuum line or ignition coils going out?
