I have a 2000 SE with a 3 year old jasper rebuilt 3.0 flexfuel in it. I seem to have a problem with keeping the oxygen sensors working.I've replaced 2 in 3 years. Is this a known problem of some kind with these engines?

Is your engine sipping coolant, or have you used, or sprayed a silicone product under hood, that the engine could have ingested???? either of those two things are known to take out O2 sensors.
