Im going to apologize in advance. My laptop took a crap about 6 mo ago and I've just used my phone ever since to get online. My phone wont allow individual forum room searches so I cant look this up with out getting 3000 pages of info.

I have a CEL on for 02 sensor. I'd like to replace them all at the same time. Autozone has Bosch in stock. Is there a better brand to get?

 

Sorry 99 Disco 1

 

Will Tillery, $75/ea new

 

Amazon, $50 each new.
BUT, beware that 98% of all O2 codes on your model year are caused by weak spark and a simple tune up cures that code most of the time.

 

Fair enough. And as much as I abuse amazon to buy pretty much everything non-perishable in my house (yaaay Prime!) whenever I can send business to a reputable rover supporter I do. I honestly don't trust some of the Amazon marketplace vendors to send me the right part, though they do offer amazing customer service to rectify any discrepancies.

If you're going to replace the O2 sensors, you might as well do a tune-up while you're in there if it's been a while.

 

I understand where you are coming from.
For me its all about the bottom line.
Each to their own, no harm no foul.

 

Well tune up was in the works any way so I'll do that first. Thanks guys I really appreciate the advice.

 

Only replace the two upstream sensors (assuming you need to replace any at all). The downstream sensors wont help your truck run any better at all since they're just for emissions. Worry about those if and when you go for emissions testing.

 

Yea unfortunately here emissions testing is every year. Thats why I was gonna do all four

 

How does one get ahold of said Will Tillery?
