Popping on deceleration!
Car is 996tt. Does anyone know how to fix a backfire problem which happens on deceleration? Do you guys think a dirty fuel injector or spark plug may cause this popping (causing unburnt fuel to flow into the exhast)?

Mechanic said there was a leak in the exhaust. However, after fixing the exhaust leak, there is still a little bit of popping when decelerate. Do you guys think that this may be caused by a bad "air injection diverter valve"? What exactly is an "air injection diverter valve"?
