2001 Dodge Grand Caravan Question: bad fuel mileage

Yes I still get these codes. There are two oxygen sensors the other reads bank two. The code I get is for bank one. thanks for the reply hope to get more info from you -

If the P0172 code is set for one bank only, then the O2 sensor wouldn't be the cause. Check for vacuum leaks on that side (bank one) of the engine or a leaking injector. (please use the "Add Response" button on the question page, thx) -

I just had it smoke checked and there were no leaks. I also changed a bad injector about a month ago the rest were fine. Was kinda wondering about the air charge sensor I think that is the name for it. Thanks -
