It's an 02 sensor. it measures the oxygen content of your exhaust for the ECU to adjust fuel trim among other things.

This image is an 02 sensor listed as for a 1984 to 1987 Buick G/N Granted, it's not identical but that is an 02 sensor you have there

It looks like the old noise suppressors that they put on the coil of the ignition system, however your is broken, the mounting tab is missing that is what the two little holes are in the body of the condenser. If you don't get any radio noise from your ignition when it is running then you don't need it.

it does not look like a o2 sensor.. could be a knock sensor.

OK I'm convinced, You guys payed more attention I should have enlarged the picture.
