RPM fluctuations while in park can be caused by several factors, including a vacuum leak, faulty sensors (like the throttle position sensor), or issues with the idle air control valve. These components can affect the engine's air-fuel mixture and idle speed. Additionally, a dirty fuel injector or a malfunctioning mass airflow sensor might also contribute to irregular RPM behavior. If the issue persists, it’s advisable to have a mechanic diagnose the problem for proper resolution.

Is it normal for the rpm gage to be above 0 when in park?
Yes, it is normal for the RPM gauge to register above 0 when in park. This reading indicates that the engine is running and idling, which is typical when the vehicle is stationary. The RPM can vary based on factors such as engine temperature, idle speed settings, and whether any accessories are being used. However, if the RPM is excessively high while in park, it may indicate a potential issue that should be checked.
