I took my car in to the garage to get a tune up and it still runs rough at idle. The system was cleaned out, new plugs, plug wires, and pcv valve. What could still be the problem?

Do a compression test to rule out weak cylinders.

You could say that. Serious engine repairs like valves and pistons/rings could be required.
