Hi markopolish,

What is the actual problem that you are encountering?

Thanks for responding. : ) Turns out light refers to an O2 sensor upstream from catalytic converter, near the manifold, feed mix error. Its only been 37,500 miles, outside warranty of course. Shops say they will only replace. It triggers a second downstream O2 sensor error too. Shops all quote fairly high costs to replace the one, bank one sensor one; Could it be too much salt spray in sloppy winter? To test, I replaced air filter, light came back on anyway. So just what happens really if I don't replace? More, different damage to come? I did a sample calculation if its just more fuel cost only: iif overall I lost 4 mpg (don't know what real would be), if use $2.50/gal, the extra fuel cost is 2 cents/mile, then extra expense exceeds cost to replace that one sensor in about 12-15,000 miles anyway. Thought I'd drive 100 miles to see what mileage loss is, but it's snowing again. Will it cause real damage or not? Or cascade to new damage or more over time? They say this car has 5 of these sensors total, this is just one sensor. Significant mileage loss, or not? Engine sounds a bit throaty but could be my imagination. You never know who to trust, and I just discovered this forum. Thanks.

You are welcomed. Due to overhelming questions coming in, we are sorry that we are not able to attend to all questions and some are replaied rather late.

I would like to know the exact trouble code to understand the problem to be able to make any comments.

Autozone provides free scanning services, get it done and let me know the codes.

Some might be due to wire connection contaminations as you mentioned salt sprays.

The faulty O2 sensor would not cause other components to go bad but it can shorten the lifespan of items such as the catalytic converter due to the richer fuel, and that means a higher fuel consumption as well.
