	No, it is a 3-wire heated one.  I I'm just saying that someone
said the heating part could be broken but the sensor itself could be fine.
Since I have a spare car that doesn't have this problem I could borrow its
OXS Sensor.

	Mine idles great.  Its just above about 1/3 throttle that I run
into bogging problems.  Almost like it just all of a sudden dumps a BUNCH
fo fuel into the motor and it bogs.
	I dont know if you are familiar with Carburated 2-cycles but if
you are it is similar to the feeling if your high speed jet is set to far
out and wont engage.  Fine accelerations and power when just the low speed
is activated but then when you floor it the engine bogs.  Come to think of
it, on a 2-cycle that means its running lean as the motor isn't getting
enough fuel beause the high speed jet isn't flowing yet.  (If I remember
properly)  I spose I should run it when cold and then try pulling the
plugs after if bogs to take a look at them and see what they look like.
	Anyhow, thaks for the reply
