oxygen sensor?

[jaslo]

Was wondering if anybody has replaced their oxygen sensor and if so at what mileage? Just been noticing after 56k my performance seems a little sluggish.

If there's a problem with an 02 sensor, the PCM should pick up on it and throw a code. I'd check the basics first before I condemned an 02 sensor. Adequate fuel, spark, air, and compression. How old are the tune-up parts? ie: plugs, wires, fuel filter, etc. Maybe try running some fuel injector cleaner through the system also.

 

Oh yea, and make sure the E-brake is off...Just kidding
