Why does my car backfire on deceleration?
“In general, backfiring on deceleration (as opposed to acceleration) is generally caused by a lean condition in the pilot circuit. Then when the engine does fire, these un-burnt gasses are ignited in the exhaust pipe, causing the backfire. Decel popping is caused by the detonation of unburned fuel in the exhaust pipe.
Why does my exhaust pop on deceleration?
Decel popping is caused by the detonation of unburned fuel in the exhaust pipe. This happens with high flow exhausts that allow more fresh air to be pulled into the pipe, causing the exhaust temperature to rise and detonate any unburnt fuel.
What causes a car engine to backfire when slowing down?
Rich tune with an exhaust leak or too little backpressure/too short of an exhaust which is allowing fresh air to be drawn into the exhaust under decel, providing the oxygen needed for the unburnt fuel in the exhaust to ignite. – Jus – Rebuilding your journal bearing turbochargers since 2004.

Why does the exhaust on my motorcycle backfire?
Shorty exhaust also has a tendency to backfire more because there’s not as much pipe length for the turbulent air to become more smooth like the motorcycle was originally designed for. Engineers put a specific length of exhaust pipes on motorcycles because that way it will get the best fuel efficiency.
What causes a dsmtuner to backfire when slowing down?
Backfiring can be caused by to many thing, TPS, Exhaust Leak, Boost Leak, Spark, which can be plugs, cable or coil, also the EGR plays a little on this,,, all this can cause a rich mixture which rich is what makes to Backfire when Deceleration and Lean can cause backfire when acceleration. Loading…
When does a carburetor backfire what does it mean?
Don’t be mistaken… After-burn is similar to back-fire, which is the burning of fuel in the intake port of the carburetor. Both conditions occur when a very lean air/fuel mixture burns so slowly in the combustion chamber that it is still burning when the exhaust and/or intake valves open.
