flex fuel sensor

What about some kind of fuel additive? I used to use Amsoil Diesel in a gas engine to pass emissions. Only needed one two ounce in a full tank of gas to clean up all the sensors.

Nothing that is a real quick fix, except replacing the sensor after testing the wiring and the sensor itself to see if it is actually faulty. I would buy one from a salvage yard if you don't want to spend BIG money. They are about $600.00 new.

OR you could look into converting it away from a flex fuel. You would need to replace the sensor with a straight line, reflash the ECM so it doesn't look for the sensor and replace the gas cap with a black one. Not sure what else on the 2.2 is different for flex other than those. It should have the wideband O2 sensor and that should be OK as is.

Tried using different additives, nothing helps. Sensor is marginal..sometimes it resets itself..may be even the different gasoline mixtures being used in todays fuel..

Thanks for the reply...I think I'll just stay with the flex fuel sensor and try and find a replacement at the local junk yards..
