What Is Car Engine Surging

Engine surging is when an engine starts easily and accelerates smoothly, however after a few minutes at a steady speed, it either surges in speed or misfires. Misfiring happens when one of the cylinders of an engine’s combustion cycle fails.

What causes a car engine to surge?

If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.

What is surging power in a car?

Surging is associated with a sudden increase in speed that occurs while trying to maintain a constant one. This is a sign that your fuel pump may have sufficient wear and tear and that its irregular resistance within the motor is creating an inability to maintain consistent pressure resulting in surges of power.
