I already posted here about my idle problem but I have more information but no solution.
so the problem at hand is, when you have the car in park and A/C off idles great no vibration(700-720 RPM), Put it in gear A/C off still it runs great slight vibration(700-720 RPM), Turn the A/C on and put it in gear idles like a dog turd lots of vibration(680-700 RPM), The car has no miss or hunting just lots of vibrations and it sounds like the engine is straining a bit, now something to note is when...

Idle rough when A/C is on and in gear
