Please, I'm begging you all...

In case you (the reader) are new, here's a back story so you don't have to see the other posts about this (and ):

I have a 2003 Zetec with a CAI.

Lately, it's been throwing a PO2195 code (Upstream O2 sensor stuck/biased lean, bank 1, sensor 1).

I've been searching high and low for answers, and nothing's working.

I even did some thinking, checked for vaccuum leaks. Nothing.

I don't know what to do, i'm at my wits end here.

I need someone with some experience to shoot me some advice!
