Car acts up when AC is on in idle

Hi.
I noticed when I have my A/C on, my car seems to like stutter on idle.
Hard to describe but it only happens when the a/c is on.
Anyone have any idea on what it can be?

I was looking to solve the same issue. I replaced all coils and plugs, but it still shudders at idle. Maybe a Computer issue?

Cleaning the MAP sensor on top of the intake manifold with CRC electric part cleaner solved this symptom for me. I believe MAF sensor cleaners will do the job as well. Just take the cowl off and you should be able to access the sensor.

Just replaced my spark plugs.
Will drive around and see if the issue persists.
