We have a 99 Pontiac Grand Am with 99K miles and it has been using coolant
for about a month now.

Adding coolant only seems to have prolonged the inevitable.
Now it used 1/2 gallon for the last 30 miles and the service engine light
has come on.
The car also is running poorly. It is missing badly.
I want to take it to AutoZone to get a diagnostics. Is it  safe to drive?
Any idea why it is now missing?
The oil is clean and exhaust appears OK.

I should mention the car has a 3.4 liter V6 which is known for intake
exhaust gasket problems

Sounds like there might be a leak.  You should have it checked out.
Its probably safe.  I don't think it will blow up and hurt people.

Might kill the engine if it runs out of coolant. Might think of having it
fixed or trading

It's your manifold.  Should run $600-$700.

Is there  a coolant leak? Do you see coolant under the car when it runs?

If you do not see coolant under the car check your oil. If the level is high
and discolored you very well may have a blown head gasket.
