I installed a GM 3bar, and I was rich off the charts at idle, and when you breathe on the gas, it goes off the charts lean. I got the sensor from a friend, so I dont know which part # it is, but the following #'s are on the sensor itself, can anyone plz verify for me?

On the top cover: 466
Bottom Cover: 9576-C6 and >PBT-6F30<

Thx

 

I hope you have a standalone and not the stock ecu.

 

i am using a nearly stock ecu

 

actualy thoes numbers don't mean anything, there like gm's stocking numbers. if you do a search on google you will find that out. the only real way to test it is by measuring the voltage as pressure is applied. or test it with a standalone.
