I have a few questions on O2 sensors:
1. Do the 5KTQ's have an OXS warning light? I don't see it on my car
(87 5KTQ) or in the owner's manual.
2. What's the typical gas mileage for the stock 5KTQ? I get anywhere
from 21 (city) to 25 (highway) in my car (the trip meter shows 10% more
though). Is this low? I can't imagine getting 30-35 on my 5KTQ. May
be my O2 sensor needs replacement (135K on the original sensor)? No
drivability problems, no computer error codes set, and the car has
passed emissions in the past. I would consider replacing it if I get
3. How much does the O2 sensor cost? Any suggested parts vendor?
