What causes a car to backfire through the exhaust?
This after-fire is a by-product of backfiring through the exhaust, something that was a common sight in older car models. Backfiring through the exhaust is a result of problems arising out of rich fuel mixture and out-of-turn sparking of spark plugs.
Can a turbo charger cause a backfire in a car?
A backfire condition can also occur in race cars using a turbo charger which is normal because they push the fuel through the engine which is then ignited in the exhaust system. We will cover the primary occurrence of the engine under load first.
What causes a Chevy 350 to backfire constantly?
The air intake boot or tube transfers air from the mass air flow sensor into the throttle actuator and then into the engine. If there is a problem with these parts such as a tear or rip it will allow un-metered air into the engine which the computer will see via the oxygen sensor which in turn will deliver less fuel creating a lean condition.

How does the EGR work on an engine backfire?
Backfire is one of them. The EGR system is designed to reintroduced a measured amount of exhaust gases back into the cylinders for reburn. This reduces combustion temperatures and dangerous emissions like NOx (oxides of nitrogen). The EGR valve opens when engine speed increases and closes when engine is resting at idle.
