According to Chrysler, the spark plugs should be changed when you reach 100,000 miles. This applies to 3.6L V6 engines, and the interval is different for 2.4L 4 cylinder engines.
In some cases, the spark plugs may fail as early as 60,000 miles. In such situations, the check engine light may turn on. Diagnostic trouble codes will be stored in the ECU and can easily be retrieved using a diagnostic scanner.
If you have been getting poor fuel economy or are experiencing other problems with your Chrysler 200, it may be time to replace the spark plugs.
