The whirring noise could be coming from a faulty serpentine belt or pulley. Have it checked and replaced if necessary.

It could also be an issue with the idle control valve. Have a mechanic inspect it and clean or replace if needed.

Check your air filter and change it if it's dirty. A dirty air filter can cause engine noises.
