Question about 2000 Buick Century
Is it leaking oil or antifreeze?
If it's oil at this location ,it is most likely the seal on the sealed (not used) distributor hole plug.(an easy fix).
If it's antifreeze it will most likely be the gasket between the head and intake.A little work but not bad.You will have to pull the valve covers and the intake but the heads stay on.

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.

patience , and a 13 MM wrench , you gotta get your arms in there deep , that lower bolt does not need to come all the way off , the thermostat housing has a slot at the bottom for easier access , loosen it about 3.4 of the way and you can get the housing out , experience says a premium thermostat will give you grief trying to reinstall , get a regular duty thermostat .reverse procedure.

Your IAT sensor is going to be on the intake tube.
the connector you should see is a oval two wire connector. (the normal for chevys) the other connector going to the intake tube is the mass air flow, these usually have 4-6 wires.
I can't help you with your govenor problem

This is usually an indication of "blowback" caused by worn piston rings. How many miles on the engine? There is not a cheap solution if it is blowback.
