Why would a fuel injected car backfire?
This can be caused by a faulty mass airflow sensor or a clogged engine air filter "choking" the engine and not allowing enough oxygen to flow into it. Or, it could be caused by leaking fuel injectors forcing too much fuel into the engine.
What causes an engine to backfire through the exhaust?
An engine backfire occurs whenever the air-fuel mixtureair-fuel mixtureFor gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.https://en.wikipedia.org › wikiAir–fuel ratio - Wikipedia in your car combusts somewhere outside the engine's cylinders.

What is the main cause of engine backfire?
The spark inside the chamber may not burn up all the fuel, allowing a little extra gasoline vapor to enter the exhaust, and lead to a backfire. This can be caused by a faulty mass airflow sensor or a clogged engine air filter "choking" the engine and not allowing enough oxygen to flow into it.
How do I stop my exhaust from backfiring?
- Change oxygen sensors. ... - Stop air leaks. ... - Renew that spark. ... - Check engine belts. ... - Keep a healthy exhaust.
Can spark plugs cause backfiring?
Another possible cause of your backfire is a spark plug refusing to “spark” when the exhaust valve opens. If the air/fuel mixture has become too rich, unburned fuel is left in the exhaust system. The misfired spark plug ignites the rich air/fuel mixture, causing a loud “bang” in the tail pipe.

What is the most common cause of backfire?
Backfires and afterfires are worth paying attention to since they can cause engine damage, power loss, and decreased fuel efficiency. There's a variety of factors that can cause your car to backfire, but the most common ones are having a poor air to fuel ratio, a misfiring spark plug, or good old-fashioned bad timing.
Can fuel injector cause backfire?
On the other end of the spectrum, a bad fuel pump, vacuum leak, or clogged fuel injectors could cause an air-fuel ratio that's too lean; that is, it has too much air and not enough fuel. Though this is the opposite problem, it can also cause a backfire as vapor escapes into the exhaust and combusts there.
