I don't. Mine did the same thing untill I put the new sensor in. NAPA had
it for about $40. Pain to get to. Let somebody else do it. It unscrews like
a spark plug, but it sits under the intake manifold so you will be bent over
the car for about an hour trying to figure out how to get the intake off.
There is a plastic tube that runs behind the intake that likes to break and
the fuel line may need to be disconnected. I managed to replace mine
without removing the fuel line. Did the job 3 or 4 times and then I just
stopped looking at the gauge. The sensors would keep going up.
