RPM or Revolutions Per Minute is a parameter that affects vehicle performance, closely linked to power and torque. It essentially measures how fast the engine is running. When your car is in idle, your engine should maintain a steady RPM, usually between 600, and 1000 RPM depending on the vehicle.
Engine RPM Revs Up and Down While Idling in Park can indicate various issues with your vehicle. Common causes include a dirty idle air control valve, vacuum leaks, a dirty MAF sensor, a faulty throttle position sensor, a bad oxygen sensor, or issues with the throttle position sensor. In this video, we deeply explain the common reasons why your engine rpm revs up and down at idle and how to fix it.
