My CEL came on but the van is running fine. My local Advance Auto read the codes: P0442: Evap emissions leak P0151: O2 sensor, Bank 2, Sensor 1 P0131: O2 sensor, Bank 1, Sensor 1 Googling these gives me a bunch of conflicting information and I cannot find a post that has these 3 codes together. Any ideas?

check the pcv hose at the back of the intake manifold it often leaks and will cause several idle problems

Although I recommend you buy a Haynes service manual for your Dodge, I think you will find the canister attached to the firewall or one of the fender wells.
Most of them look a lot like an overgrown spam can and it will have two connections on it.

It is probably a sensor that goes by the gas tank. I belive it is called a Fuel Vent Sensor Circuit. That should fix the problem.
