O2 sensors

Where did you guys buy yours from? I need to replace the front passenger side ones and not much aftermarket ones out there. And what's the diff. between the stock ones and the widebands??

thanks

get stock AC delcos. Don't bother with bosch or any other non OEM 02. too many people have issues with them. Wideband 02's are not set up to work with your stock PCM. Well, really the stock PCM isn't set up to read wideband since it uses a different voltage range.

Your PCM still needs a regular O2 sensor input, the wideband isn't something you'd want to run fulltime as they have a finite lifespan.

I'd also recommend sticking w/ Delco regular sensors. I'm testing Denso ones and thus far I'm happy, but not enough runtime yet for me to recommend them over Delcos.

I have run the Densos for a year and have been happy with them.

Get the OME ones
I had the Bosch ones and they had a low voltage signal after 6 months, I have ahd the GM ones for over a year and perfect.

Widebands can work with stock ECUs if the controller has a narrowband emmulation mode. This output simulates what a narrowband would be doing under the current conditions to the ECU. You can use is to modify the AFR in closed loop by setting the narrowband switching point in the emmulation to values other than 14.7AFR.

Widebands are used as OEM parts in VW's and Audis. Under normal conditions, they live nearly as long as stock narowband sensors. But, if they are constatnly being run very rich, they do age and eventually fail.
