When ever your using fans, heat or air It requires more power to operated through system, more demand on engine. If has been idling rough, the a/c has nothing to do with the rough idle problem so much, as it just puts more demand on engine, to lower idle, I would check have fuel injection cleaned, possibly air filter and oxygen sensor replaced. Let me know, if this has helped. Thanks mike from fixya.com

Sounds like possibly you might need a new O2 sensor. Have it checked out

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.

I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

2001 Nissan Altima shuts off in hot weather

it is the cam position sensor...the telltale sign of the failure is that it happens when the vehicle is warm and has been driven for a while. Sensor is about 40 bucks at the auto parts store, make sure the replacement sensor is metal, not plastic.
The main symptoms of this sensor failing are rough starts, rough idling and not starting at all especially when warm.

I have intermittent rough idle on my 2003 nissan altima. car shakes in gear at stop, mostly fine in neutral.

Replace the spark plugs, spark plug wires, distributor cap, and rotor. Next, check the idle air control valve and replace it if found faulty. If it still shakes, have the timing checked out

Rough idle, dies when trying to give it gas

it'll either be your ignition system (spark plugs, distributor cap, etc) or more likely your fuel system (most likely your fuel pump or your fuel filter)

1997 Nissan Hardbody has rough idle/surges/stalls

the 2001 altima is what i have and I had the same problem as you. turned out to be a bad head gasket factory used cheap ones for a few years before they found the problem. one way to test this is to get a can of carborator cleaner and spray it around the area where the head meets the block under the intake problem should be around the 4th cylinder or close to driver side. if the head gasket is bad the rough idle will smooth out while you are spraying the head.
