I have been having problems with the Bosch sensors. Instead of switching them out when they go bad onch a month or 2 weeks, I thought I bought AC Delcos when I ordered but ended up with Delphi's ES20022. They look way different than the Delco's or the Bosch's.
Has anyone used them yet? Are they any good?

 

I think you recieved one of the same as mine, I made a thread about it here: https://www.camaroz28.com/forums/sho...d.php?t=586464

 

Thanks for the link.
How are they holding up?
I have the Bosch in my car now, and they foul out after 2 weeks.

 

I have problems with the bosch too. Post up your results with the diff. brand.

 

They have only been in my car for 2-3 weeks but no problem yet. They should be equal to delcos.

 

I was talking with the Napa auto parts manager the other day and he
tells me there are only two manufacturers for O2's: Bosch and, well, I
forget the name of the other manufacturer. Basically, he said that Bosch
manufactures the majority of O2's, but they get re-branded, so that
ACDelco O2 is probably a Bosch with 'ACDelco' stampings.

Something to consider about O2's with coated headers - rumor has it
that the coating's particles are what clogs the O2's.

 

no delphi is who makes the o2's for ac delco.

 

You need to fix the problem, otherwise you will be swapping in o2's regardless of brand. Is your car running rich?

 

GM spun off a lot of their OEM parts divisions into "Delphi", an independant, publicly traded company that went Chapter 11 in 2005.

 

A/F is at 13:6 at wot and 14:0 normal driving.
What happens is that the o2's get "lazy" after 2 weeks and goes down hill from their.
I recently switched to coated headers, and thats when the fun began with bad o2's. The headers are about 3 months old. Before that it was the uncoated Pacesetters.
