lost power

[csxmoose]

about a month ago i lost a oxygen sensor which i recently ordered. problem is, 3 days ago i've notice a considerable loss of power. seems like it takes more pressure on the gas pedal before it shift into a lower gear for passing and instead of shifting one gear down it right away wants to shift balls out so i'm screamin down the street. instead of the steady torquey shift with gradual power. could this be from the o2 sensor?


its either, no power, or balls to the wall haulin ass?

don't get me wrong, i love haulin ass, but around town i don't need to drag racing....


and btw, my sensor showed "bank 2 sensor 1". this is the passenger side header sensor... no?
