anyone know of a good place to get O2 sensor for a good price, did a quick search and found nothing to impressive. Usually use AB $69.

(just got a P0150 code, RH front)

Thanks

 

Mid $65 range is about as good as it gets. How many miles on your truck?

Thanks, right now I'm at 92K

 

You should change out all four O2's at the same time if you want to regain some lost power and milege. If you are looking for a bandaid amke sure that you use the same make O2 as you replace them one at a time. At the 100,000 mile mark they should all be replaced.

Just saw that you have a Disco II I dont know a thing about them.
Had put up what was needed for the Disco I

 

They are $65 at Rover Connection.

 

I don't under stand your post?

Hi I need to change my o2 sensors also. How do I know if I need 4 or 2 of them and which one's? Seems like there are a few of them for that year? I have a 1999 Disco 1. Thanks.

 

Welcome to the club... I as well have a 99 Disco One. You will need four of the little buggers and the bad news is that you're going to be payin about 95 bucks each at roverconnection.com for them. Their prices seem to be the cheapest out there right now for them( now i know someone is going to reply and say "well you can use a generic and re-wire them---dont get me started) As was stated above, you should replace all four at once.

 

On recommendation per DiscoMike, I replaced all four at 106K on my 2000 D2 during top-end rebuild. The right engine bank was showing black plugs, and the engine started to idle rough, however, all four is the way to go. [sm=smiley20.gif]
