Need help have a cel on and 2 codes bank 1 and 2 system running rich.
Like it says its running 2 codes. P0172 & P0175 system running rich bank 1 and 2. well i was told it could be o2 sensors or a maf sensor. Or fuel pressure. Well i cleaned the maf sensor still didnt help, and im stuck guys and dont really have the extra cash to spend on stuff, but its running like a dog 
and isnt getting that good of gas mileage. Need the truck running good again. Thanks guys.

That's it on the frame. By looking at it I can almost guarantee that it's corroded pretty bad on the back. Being an electrical component, it can kick out all sorts of symptoms depending where the corrosion is. I had one go that just threw a misfire code and rich bank 1. Buddy had one go that threw a lean code, low pressure code, and an evap code. Others just completely die on the side of the road.
Don't bother spraying it with anything - just swap it out. It's a time bomb even if it has just started to go.
