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.

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
