Hey, Dave,
I had the same problem, and I was told that once I replace the sensor
and check that there are no obstructions in the exhaust tube -- if it's
the front and something did get in there, you have bigger problems <g> -
- all should be good. I changed the sensor myself, saved a wad o' cash,
and i am even getting better gas mileage.
Good luck,
Z
