So far continuuing my education; having learned about evap system, fuel cap and tank design, MIL & ECo illumination. Disconnected the battery, one hr. during lunch, the MIL extinguished. ECO light and other MPG readings back to normal. Ordered an OBD so I don't have to go to Napa, Autozone, or O Reilley's (all helpful). Now wait and see if light comes back.
you can delete codes all day, or, every time they come on....it's not fixing the problem. My 2011 ram had a similar issue and it was a vacuum line from the top of the tank to the engine.
the reason mine went bad was as i was driving on I75, i had no choice but to run over a black plastic bag some one lost. Inside the bag was a blanket, and that wrapped around the driveshaft, which in turn ripped that hose off. My milage went down to 10-12 MPG...on the highway! UGH I fixed it by cutting off the bad ends and adding a hose to those ends. it worked..lol. About a year later i traded it in.
