Folks,

Here's a possibly dumb question: what might cause the O2 sensor LED to not
light when i turn the key to start the vehicle?

All the replies to my earlier question about degrading performance as the
engine warms up seem to center on the temp II sensor and the O2 sensor.

The vehicle had passed an emissions test in St. Louis, Missouri about two
weeks before i bought it (yep, saw the printout), so i'm thinking that the
O2 sensor is working... but the dashboard LED has never lit. This is only
mildly surprising since the oil LED was MISSING entirely when i bought the
vehicle.

Before i start tearing things apart i figured i'd ask first.

As always, many thanks.
