My 'Lark is running very well but tends to pop out the exhaust upon decelleration. Pop is not really out the tail pipe, it sounds more like around the header collector, to be specific. I do know that the car is running lean, as the plugs are white. This popping is kind of lame sounding, and I'd like to know if there any tips to get rid of it. Is it my 2.5" "club" exhaust with headers and very free flowing mufflers that is causing this?? Thanks!
