Any rubber hose that is attached to the upper intake and any air hoses coming in from the air filter box. Check the PCV valve and associated hoses and vacuum hoses on the firewall. With the engine on, you can move the hoses around and listen for hissing or change in idle.

try cleaning the MAF with the correct cleaner and make sure the air filter box is closed properly
