HOW HARD IS IT TO GET TO AND REPLACE THE #2 O2 SENSOR ON A '97 ?

1997 Cadillac Deville • 82,000 miles

The car is driven very little, as the mileage will indicate. A local parts house read the "service engine soon" light problem and the #2 O2 sensor was what was indicated.

Do you have code #? #2 sensor is not enough info.

No, I do not have the code. The parts guy showed me the sensor, and said that it is in the rear exhaust manifold. How to get to it is the main question. It must be near it's plug in - since the leads are only about 12" long.

Nope. Other than from the top (nothing really visable past the valce cover). And laying on my side - I can see the Cat converter. But the exhaust coming to it has nothing. Almost has to be in the manifold above that.

Yah it's a bugger. Try getting behind from fender area. Use hand to try and feel it on manifold.
