Is the Popping Sound from the Exhaust Pipe Caused by a Misfiring Cylinder?

Not necessarily caused by a misfiring cylinder; it could also be due to other reasons. The popping sound from the exhaust pipe might be caused by fuel line blockage, poor flow, or issues with the stepper motor, dirty throttle valve body, or air leaks. Engine Misfiring Cylinder: If a cylinder in the engine stops operating, the exhaust sequence of each cylinder will be disrupted, resulting in a popping sound from the exhaust pipe. Exhaust Pipe Damage: Since the engine exhaust emits high-temperature, high-pressure waste gases mixed with some backfire explosions, it must be muffled and purified through the exhaust pipe. When the exhaust pipe is damaged (with gaps), exhaust gases will spray out from these gaps, causing the popping sound.
