Are you using the engine for braking? Are you blipping the throttle to match revs prior to letting out the clutch? This can cause a backfire if you spin the engine to high rpm's with little or no throttle. A leak as 99 911 said could also be the culprit.

Mechanic found an exhaust leak and fixed it. But there is still a little bit of popping. I've found some articles on the web which said that popping on deceleration could be caused by a faulty air injection diverter valve. What do you think? Is there an air injection diverter valve in the 996?

this was a great thread; laughed more than in the first part of jumping between letterman and the other guy.

I blip the thottle to match revs but never enough to cause a backfire...how or why would an over rev cause a backfire...just curious?
