Hello,
When someone states that I may have a "Lazy o2 Sensor/s", what does that really mean?
1. That the sensor is slow in responding!
or
2. That the sensor is showing less O than there actually is and thus the ECU is dumping more fuel.
or
3. ???
I have a 2006 Silverado 5.3L V8 with 4 O2 sensors. When I monitor the O2 sensors with a scanner, the 2 sensor after the catalytic converter are around 710mv with no HHO. When I add about 2 LPM of HHO, they drop down to about 670mv.
The mv reading of the sensors after the catalytic convert do not change much, but the O2 sensors before the catalytic convert jump around like crazy. About 69% of the readings range 500-790mv, the other 29%, the readings are 10-250mv. 2% of the readings are in the middle.
Is this normal for the before catalytic convert sensors to be this erratic?
Since I have a ODBII Tuner, I am thinking of just manually leaning out the fuel mix to over come the extra O. Will this work? But, my concern is that when I have no HHO, that it will be to lean and damage the values and pistons.
Thank you and looking forward to your response.
Have a great day!
