The idle RPM for a 2002 Chrysler Concorde will vary slightly depending on the engine (2.7L V6 or 3.5L V6) and any modifications or issues with the vehicle. However, a
normal idle speed is typically between 650 and 850 RPM.
If your Concorde's idle is significantly outside this range, it's a good idea to have it checked by a mechanic. An excessively high or low idle can indicate a problem with the engine, sensors, or other components.
