This can happen for many reasons, however usually a loud pop or backfire is a sign of a lean fuel condition or an ignition timing problem. A lean fuel condition can be caused by a faulty mass air flow sensor or throttle position sensor.
An ignition problem can occur as a result of a bad crank position sensor, faulty ignition coils, and many other things.
This issue should trigger a Check Engine Light which will register some fault codes in the car’s computer. I would recommend having an expert from YourMechanic come to your home to diagnose any trouble codes using a scan tool which will help to download specific details as to which parts have failed.
