Adjust the idle screw.
Needs a Tune up
NAPA and Precision Tune and Auto Zone have a free analyzer check. Use it.
Might be time for a tune up, new plugs, fuel filter, pcv valve, cap and rotor and wires if aplicable.
Could be the mechanic set the throttle control too high, so your car idles at a higher RPM than it used to. Timing was set wrong. your car should be better after a tune, perhaps the tuner made a mistake or did not do the tune correctly
that is a computer problem you will need the proper reader for it and that is about 4000 so just take it in it is only about 40-60 dollars and they will tune it right

More than likely... Tune up, or vacuum leak

I've had this problem a couple of times with my 96 Ford Explorer. Either: 1. The car needs a tune up 2. A sensor is out and the car needs a tune up 3. Something is wrong with idle . . . needs to be checked The real answer is that you need to get to a mechanic asap . . . When the idle was loose, the car would die, but when a tune up was needed it ran rough without fully dying . . .
It probably needs a tune up. My 1998 Mazda 626 was idling very rough, so I did a tune-up by replacing the spark plugs and wires. This made the engine run better, but the rought idling continued. I took it to my mechanic, and he found a vacuum leak somewhere, and $270 later, it idles smooth as glass
