Gents,

Looking to change the O2 sensors, looking at FCP Groton, found out that there's a Walker model, cheaper. Is going that route really worth? Are they has good as Bosch's?

Tx for the feedback!

Avoid the Walker...only the tried and true Bosch....read about to many people who still get an 02 code and problems out of any other. Btw, how do you know your 02 is bad...that code can be set by numerous other things- bad vacuum lines, bad MAF, etc.

Reading code 4-3-6 as an error, car being 230K I figured out it was the sensor, however, a leak in the exhaust or intake, might be a more probable cause.

Thanks for the heads-up!
