What causes the feeling of fuel interruption when accelerating in a Cruze?

[MelanieLee]

The reasons for the feeling of fuel interruption when accelerating in a Cruze are as follows: 1. Fuel system malfunction: A clogged or waterlogged air filter reduces air intake, leading to an overly rich air-fuel mixture, incomplete combustion in the engine, and poor acceleration. In this case, the exhaust pipe emits heavy black smoke. Cracks in the fuel line or loose connections causing air leaks, as well as insufficient fuel pump pressure, result in poor fuel delivery and affect acceleration performance. 2. Electrical system malfunction: Issues with the mass airflow sensor can reduce air intake, causing the air-fuel mixture to be too rich or too lean, affecting acceleration performance. Damage to individual cylinder spark plugs, meaning a misfire in one or more cylinders, also impacts acceleration. 3. Mechanical malfunction: Wear and tear on engine components such as valves, cylinder liners, pistons, and piston rings can lead to insufficient cylinder compression. Excessive intake valve clearance or insufficient exhaust valve clearance can also negatively affect acceleration performance.
