10 Causes of a Car Losing Power When Accelerating

  • Clogged Fuel Filter
  • Clogged or Dirty Air Filter
  • Clogged catalytic converter or particle filter
  • MAF Sensor malfunction
  • Oxygen Sensor malfunction
  • Faulty fuel injectors
  • Faulty fuel pump
  • Low cylinder compression
  • Faulty turbocharger/boost pipe leak
  • What happens when your car loses power while driving?

    The most likely issue is a clogged fuel filter. The purpose of the fuel filter is to ensure that dirt and debris stay out of the fuel system, so over time, it may need cleaned or replaced. When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive.

    Why does my car lose power when accelerating?

    A loss of power is most apparent when you're accelerating, and can be due to a number of reasons including air flow into the engine, fuel flow and even faults with the exhaust system.

    What does it sound like when your fuel pump is going out?

    Bad Sound: The first sign will probably be a sound. It's normal for a fuel pump to make a low humming noise, and you might be able to hear it coming from the gas tank area. As a pump begins to wear out, that sound can turn into more of a whining or droning. A lack of fuel can cause the engine to misfire.
