my check engine light cam on bout a week ago and now i have a slight misfire at times that comes and goes had the code read it tells me it the bank 1 sensor 1 where is this located can any one help thanks
Bank 1 should be the upstream sensor. If you have a misfire, there are other issues you need to check, such as a cracked valve seat, misrouted plug wires, or a clogged cat.
FWIW - O2 sensors should be changed every 50 - 65K miles.
Replace the O2 sensor quick. Because if you don't already have a clogged cat , you will. After you replace it , run some Techron + through it for a couple tank fulls and you might get lucky.
