Lean Running on 3 Cylinders

[tylerdurden]

Hi All,
I have a 1992 SVX throwing a code 37 (left side O2 sensor). The sensor is pegging itself at .007V, indicating an extreme lean condition. There is no fluctuation to the voltage. I’ve confirmed that the sensor itself is good (switched sensors side to side) and verified the wiring is good (voltage readings are the same at the sensor as they are at the computer). The right side bank is functioning perfectly. So my question is what would cause a lean condition on just the left bank? I pulled the spark plugs and they all looked good. I pulled the fuel injector leads off one by one, and the engine stumbled and ran poorly with any injector disconnected. I have no drivability or other issues, just a code and a check engine light. I’m planning on a road trip tomorrow evening so any ideas before then would be greatly appreciated, but more importantly, am I running the risk of damaging the engine if the problem is not fixed right away? Thanks, Cory
