Rough Idle Upon Start Up
My 2007 LX just developed an issue where the idle is rough for about 15-20 seconds after cold start up. After this the idle is smooth and runs with no issues. I searched and found some similar posts, which mostly pointed towards a bad O2 sensor, however the others were accompanied by a check engine light. I am not getting any error lights. Any ideas what the problem can be before I make an appointment with the dealership?

Another observation. I started up the car today with the A/C off and no rough idle. When I turned on the A/C it began to idle rough. Again, this only happens for a very short time then smooths out. Possible alternator or battery?
