Re: Oxygen Sensor
In my opinion brand matters. Bosch 13077 and all my problems went away. RockAuto.com. $30.99

Re: Oxygen Sensor
I used to use Bosch O2 sensors, but would regularly see the sensor drop signal in my datalogs. I could see strings of 0mv at times. Switched to AC Delcos and have not ever experienced that again. This was not just one sensor, but several, and at different times.

Re: Oxygen Sensor
Just to be clear, you will not notice the issue I describe w Bosch O2s as u drive. It is not something that overtly causes a drivability issue. But it is something you can see as you are datalogging. The O2 signal would drop to 0mv on one side or the other. So the ECM would drop out of LEARN and go open loop at times.
I discussed w some tuning gurus, and was recommended to use AC instead. Have not experienced the O2 signal drop since. And there was a difference in the resulting VE map.
