code p0171

so i just pulled that code which says, System too Lean (Bank 1). A lean air/fuel mixture has been indicated by an abnormally rich correction factor.

after i bit of a search i found that it is probably my 02 sensor which would explain why i have been getting 9-10 MPG. i emailed kolak the other day about getting a new sensor and he hasnt gotten back to me yet. i went through almost a full tank of gas in 2 days and cant really wait too much longer.

can i just get it at autozone or something? how much can i expect to pay there and how long can i expect it to last.

is there anythign else that could be wrong or that i should look for?

Im 20 with a 2000 Grand SOLD!
