Chrysler Town & Country 3.6 V6 Engine Spark Plug Replacement Guide

Symptoms

Typical problems you may experience if you have old spark plugs on your fifth-generation Chrysler Town and Country.

• Check engine light on
• Check engine light flashing
• A decrease in fuel economy
• Poor acceleration
• Engine shaking or vibrations

Why change the spark plug? 

Besides the fact that you may be paying more money at the pump, it is important to change the spark plugs at the recommended interval (100,000 miles) to avoid engine misfires and other engine problems.

If you ignore changing your failed spark plugs in your Chrysler Town and Country, your engine will start to shake if it is running on only five cylinders. This will trigger the check engine light. Get your van checked by a mechanic or replace the spark plugs as soon as possible. When this happens, one or more fault codes may be stored in the engine control module. You can retrieve these codes yourself by following this guide on how to diagnose the check engine light.
