i got this code for about 2months now. but i dont have a sub-o2 sensor. i only have one in the exhaust manifold and i replaced it. i reset the ecu and it came on in about 2weeks. has anybody had this problem??
dont you also have one in or near your 2nd cat, under the car?

According to what I could find, the 95 GT does indeed have two cats -- I also thought the federal standards were only one cat, one O2 sensor.
yea i had the car on a lift and i walk around under it and couldnt find another one. (o2 sensor)
