Think there is a rubber tube / hose that connects the air filter box to the throttle body . Look at that tube / hose ( maybe 3" diameter ) . Common fault for AVEO and Sonic to develop cracks / splits .

I think this is the revised GM part # for the Sonic ?

Chevrolet GM 12 15 Sonic Air Intake Outlet Duct 94537633 | eBay

Not sure for the part # for AVEO ?

God bless
