Just curious to see if anyone else has had a check engine light come on with their 15-16 6.7 with a code flagging "PO170 Bank 1 lean". Its still covered under warranty but due to the lack of knowledge at the local ford dealers just wanted to get someone else's take on it before i took it in and they started hacking away at my truck. Ive changed the fuel filters three times and the truck has 14k miles. I did install a KNN air filter which i though could be causing the problem but according to KNN, it won't cause any problems. The light will go on and off but still flags as a historical code when check engine light is not on. Light is currently on and it does seem to derate the truck. Planning on taking it in soon. Thanks for sharing your information!
