[QUOTE="SRAD97750, post: 230953, member: 425"] The popping you hear is referred to as 'Afterfire' as it happens in the exhaust after the common power stroke. A backfire refers to the uncontrolled explosion coming BACK out the intake. These can be very damaging to components and people. Big 4bbl V8s love to backfire right in your face. Afterfire is common in over rich conditions or re-ignition situations where there is too much fuel in the exhaust. It can also happen if the valves are hanging, or too tight. The combustion chamber literally is open to the exhaust through the hanging valve that was supposed to be shut. Back fires are common in lean situations as the over-stoichometric fuel condition can burst quickly back through the open intake valve that is feeding the hot cylinder. -BIG DAN:thumb: [/QUOTE]
