Does anyone out there have any info on how to replace the oxygen sensors on my 2001 4x4 V10 excursion?

 

Welcome aboard......Should be pretty straight forward....screw out.... screw in.....have you located it ? I am a diesel....but most 02 sensors are in one of the exhaust manifolds

 

A bit further info... you want to replace the sensors between the engine and cats; not after the cats. No need unless you are getting a code for those. Also, if you can't loosen the sensors on a cold engine, warm it up for a couple minutes and try again.

 

Thanks,
Gonna give it a try this week end!
