got my exhaust installed today. I have a check engine light on. My 2nd 02 sensor is not installed yet. The one on the car has a bracket with two holes and the cat I have has a threaded hole for the sensor. Do they make one for the car that has threads? I found one at the parts store but it only has one wire. 95 st. 7afe

On the OBDI 7A-FE you have an one wire O2 sensor that's in the manifold, then a catalytic converter at the base of that manifold and downstream of that O2 sensor. Then you have some down-pipe and then you have a two wire O2 sensor then a little further there's a small catalytic converter that isn't monitored. If the first one is just a pre-cat why would it be monitored? Even on OBDII cars I've seen pre-cats not be monitored.
