Question about Chrysler Town & Country
There is something you can do if indeed the mixtrue is rich. Try introducing a leak in the intake, this will cause a slightly leaner mixture to the engine. Reset the code, and do a drive cylce. If the code comes back as being rich then, it is the 02 sensor that needs replacing. Since 02 sensor are expensive, you can confirm by monitoring its fluctuation. A healthy sensor would have a higher valley of fluctuation and close together. A "lazy' sensor is just the opposite. Also check the fuel pressure regulator, since that can cause rich mixture as well. Dirty injectors can also cause a rich mixture. An overly advance timing can cause a rich mixture reading as well because it lowers the operating temp of the catalytic converter. A dirty air filter can cause a rich mixture. A faulty CTS( coolant temperature sensor) can cause a rich mixture, for example by sending a high resistance reading to the computer therefore resulting in adjusting the Pulse to the injector as if the engine was cold.
