99' Intrepid occassional exhaust smoke

While waiting at red lights sometimes when I take off there will be a small
( sometimes big )
puff of black smoke, sometimes none. I have had a few different reasons &
prices quoted, and wonder if I should just trade it in or if it's worth
keeping and repairing. It has 88,000 miles, and is otherwise in great
condition.
Any ideas about a reasonable cost on repair?

"Black" smoke would usually be an indication of too much fuel, or "rich",
condition, and/or lack of sufficient air, such as on old carburetor engines
when the choke wouldn't open.
