Idle air control, MAF, Throttle Body, Throttle Position Sensor, PCV Valve may need cleaned, Tune Up if needed. Plugs, Plug Wires, Fuel & Air Filter, If any check engine lights are on, stop at auto-zone to be scanned, If there is a code, check it and clean it & look for bad connections before replacing. Look over the engine bay real close and try to see if anything looks questionable, Or unhooked connectors. Check fuses.
Check the PCV tube. These cars have a problem with that tune. It creates a vacuum leak
You may want to check your airflow sensor for moths ... I broke down going up a hill this little guy got into the airflow sensor somehow.
