have the car checked out, it could be a bad o2 sensor or a plugged converter.
Not much info to go on but I'm assuming the vehicle has three 02 sensors, one after each bank of cylinders on that V6 and one after the catalytic converter. Bank 1 sensor 2 would be the 02 sensor after the catalytic converter. This B1 S2 monitors the catalytic converter activity. It could be the catalytic converter is at fault. It would be of help to know what the code # was.
It could, yes.
Could be catalytic converter Could be battery
Could also be plugged catalytic converter Spark plugs and/or wires Timing chain Could also be plugged catalytic converter Spark plugs and/or wires Timing chain
The catalytic converter on a 1994 Buick LeSabre can be removed to be replaced. It cannot be removed permanently from the vehicle. Removing the catalytic converter will cause the vehicle to not run properly because there are oxygen sensors attached to it that the car needs. Also, removing the catalytic converter permanently may violate state laws against pollution in some states.
Post Catalytic Converter O2 Sensor seems to be the most likely issue. Could also be the catalytic converter, or an exhaust leak. The cheapest part to throw at it is the O2 Sensor. (cheapest place I've found to get them is autopartswarehouse com)
