Hey what up people,

I drive a 93 hatch with a LS motor in it. Recently I put the thermostat back in because of the recent cold weather. Now that the car has been running at normal opperating temp its been throwing code 1 (which I believe is 02 sensor.) Do you think that my car may be running too lean as it warms up?

 

Code 1 doesn't tell you whether the engine is running rich or lean, just that an error has been registered for the O2 sensor circuit. Check the wires and, if fine, try replacing the O2 sensor.
