Idle RPM is typically higher when the air conditioning (A/C) is off because the engine does not have to compensate for the additional load that the A/C compressor places on it. When the A/C is engaged, the engine works harder to power the compressor, which can lower idle RPM. Conversely, with the A/C off, the engine can maintain a higher RPM more easily, resulting in smoother idle performance. Additionally, some vehicles are calibrated to adjust idle speed based on various operational conditions to ensure optimal performance and efficiency.

What is the idle RPM of a 1997 Jeep Grand Cherokee Limited 5.2L V8?
Correct low idle speed should be in the neighborhood of 750-800 rpms. A bit higher when the engine is cold is acceptable. Anything higher, above 1000 rpm probably indicates an issue that needs to be addressed.
What is the usual idle rpm on a diesel engine?
The usual idle RPM for a diesel engine typically ranges between 600 to 800 RPM, depending on the engine design and application.

What is cold idle rpm for 2008 Nissan 350Z?
The cold idle RPM for a 2008 Nissan 350Z typically ranges between 1,200 to 1,500 RPM when the engine is first started and still cold. As the engine warms up, the RPM gradually decreases to the normal idle range of around 600 to 800 RPM. This higher cold idle helps ensure proper engine performance and emissions control until the engine reaches its optimal operating temperature.
