Fuel INJ sys left bank:lean
does anyone know what this is and what it means?, i just had my tranny rebuild and i take the car home to a CEL...

 

Sounds like it could be an impending O2 sensor failure.

thanks, so the left bank is the O2 sensor on y pipe closest to bumper or farther?

 

Can't remember for sure. I believe it's the one closest to the Front bumper. I always imagine the engine turned with the crank facing the front, like a rear drive car. Then the right side is the passenger side which would be the firewall side if you turned the engine 90 degrees CW from above. The left side would then be the front bumper side. That's the easy one to change if I'm correct. Maybe someone else here can remember for sure.


Edited for clarity

 

 

This picture is about the coolant temp sensor. Has nothing to do with the O2 sensor !!!
