Why Am I Experiencing Rough Idling?

A rough idling engine can be a stress-inducing concern because it usually points to some sort of engine problem. In order to determine whether or not rough idling is what you are facing, below is an example scenario.

Right after you start the engine and before you switch gears out of park is an instance where you are always idling. Idling simply means that your engine is running, but your vehicle isn't going anywhere or engaged in any gear. When idling normally and correctly, your RPMs should be steady. However, if your parked car does the following, you are experiencing rough idling:

  • Vehicle shakes or vibrates
  • RPMs fluctuate rapidly
  • Skipping or slipping sounds

There's no doubt that you can miss the above symptoms because the effects of rough idling are "rough". As soon as you notice your car idling rough, you should immediately take your vehicle to a trusted auto professional. At Integrity Auto Services, our skillful technicians can properly diagnose your idling problem. 


Below are some of the most common reasons why a vehicle may be idling rough:

  • Filthy fuel injectors
  • Wrong idle speed
  • Vacuum leak
  • Old or worn spark plugs
  • Failing fuel pump
  • Dirty fuel filter
  • Electrical problems
  • Malfunctioning air sensor
  • Faulty oxygen sensor (O2 sensor)
