Hey everyone, been gone for a bit due to life, but still loving the T&C. But now I've got a couple of issues. It has popped a P0456 code, and I've found that it's an Evap System code. Yeah, fun to figure out what it might actually be. Now, on my last tank of gas, I only got 13.3 mpg. Could the two issues be related? Or is it more likely that the bad mileage is due to probably needing spark plugs. It's got just over 100k on it, and I'm guessing they haven't been changed.
