Insufficient fuel.

What can cause a lean fuel mixture?

There are five factors that could cause a lean mixture to occur.

  • Fuel System. A malfunctioning fuel system can reduce the amount of fuel coming into the engine, causing a run lean condition.

  • Air Mass Flow Sensor.
  • Computer Malfunction.
  • Air Leaks.

  2. Sluggish acceleration.
