Brian, that is an EXCELLENT picture showing the missing Air Flow Sensor Gasket. You guys should ALL print or save this picture for later reference. The AF Sensor gasket is just two metal plates moulded into a rubber gasket that is .600" thick. It mounts the throttle body to the SC. The gasket can crack at the metal joints and then you have an air leak. Once it gets a crack it can/will grow until you have two pieces. DO NOT twist on the gasket when you are working on your throttle body or on your intake system. Thanks again Brian.
