bosch o2 sensor

[timmack]

last fall i changed my drivers side rear o2, and about a month ago i changed the passenger side. gone through 2 tanks since i changed the passengers and both tanks have given me 18+ mpg, whereas before i was consistently getting round 15-16 tops. no other changes, same gas. i bought a bosch part #15727 for $55 + tax, the universal kind that you have to wire in. so if yours havent been changed in a long time or ever, you might consider it. the way i see it this will pay for itself in about 2 months. just a thought with gas prices as crappy as they are right now.

Hey,

Do you think you can list the step or even a diagram how to fix . Btw where it located.

Thanks in advance,
