SOURCE: Leaking intake gasket.
What engine is in this? Is it the Supercharged 3800 or the non-Supercharged? The gaskets themselves are not terribly expensive (GM has revised Lower Intake Gaskets) but it would help to know if its the upper or lower intake gasket that is leaking.
Its not hard to replace either, but it is kind of labor intensive and that is where most of the cost will be. If you are confident in doing mechanical work you can do the job yourself easily enough. But I have seen repair quotes range from $300 - 600 depending on where its down and the labor rate for that area.

The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

Ignition timing & carburetor adjustments are 2 of most likely culprits here. I would recommend a tune-up at a garage that has someone on staff that still knows carburetors. Too many adjustments to describe, unless you are experienced at them.
