check engine

Hello All,
Can anyone suggest what may be wrong? I have a check engine with a PO174 code. I replaced the vacuum lines with silicon ones and the code still comes up and check engine. I have a 2012 RTL. Any help will be greatly appreciated. Just returned from Deadwood a couple of weeks ago

:sour: I looked code up on my spyder app (spyder codes) & list as : system too lean bank 2 injection & fuel supply system, check that system so maybe you got some odd gas on your trip? The system waited till you were back & got a taste from your regular station & glitched?:dontknow::dontknow: Try some seafoam in your next tank of gas , it may clean whatever is acting upnojoke Plz keep us informed as to what you find or fix. Thx

Hey Bfromla,
Thank you for your reply, I filled the tank with non ethanol fuel and put about three times as much startron in the tank. It took a while but the check engine light went out but I'm still getting PO174 code. Hopefully that will go away soon also. Is there anything else you can think of before I call for an appointment at the dealer?
