Car idles between 500 and 950?

An idle speed between 500 and 950 RPM is generally too low for most modern gasoline-powered cars. The typical idle range is closer to 650-900 RPM, although the exact ideal range will depend on the vehicle's make, model, and year.

A consistently low idle (below 600 RPM) can indicate several potential problems:

* Vacuum Leaks: Leaks in the intake system can disrupt the air/fuel mixture, causing a low idle.

* Dirty or Faulty Mass Airflow Sensor (MAF): This sensor measures the amount of air entering the engine. A dirty or faulty MAF sensor can lead to inaccurate fuel delivery and a low idle.

* Throttle Body Issues: A dirty or sticking throttle body can restrict airflow and cause low idle.

* Problems with the Idle Air Control Valve (IACV): This valve regulates air flow at idle. A malfunctioning IACV is a common cause of low idle.

* Ignition System Problems: Weak spark plugs or ignition coils can affect combustion, leading to low idle.

* Engine Problems: More serious engine issues, like low compression or internal leaks, are also possibilities, though less likely to cause only this symptom.

If your car's idle is consistently in the 500-950 RPM range, it's crucial to have it checked by a mechanic. Continuing to drive with a low idle can lead to further engine damage or even stalling. The mechanic will be able to diagnose the specific cause and recommend appropriate repairs.
