Question about Chevrolet Malibu
I would suspect the AC compressor clutch is about to go. If it gets better with it on, it is spinning with the belt and not idling on the bearing. Take a wooden dowel, broom handle, whatever you can find, cut it about 3 ft, cup your hand over the end and put your ear in your hand, now with the engine running, be careful not to hit anything moving, put the dowel on every part, bolt, head, nut, pulley, compressor, alternator, you will find the loud one. Be careful not to hit anything, hope this helps.

Tips for a great answer:
Here are the most common causes of idle surge, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
