Vibration ONLY when A/C is on and car is in Idle.
Car is fully stock, the problem is a slight vibration (but strong enough that I feel my seat shaking) when my A/C is on and car is idling normally. When I turn off the A/C the vibration is gone. Anyone else experience this?

Turning ON the A/C causes the clutch on the compressor to engage and thus, allows the belt and pulley to turn the internal shaft and mechanism of the compressor. I would suggest that you check the compressor more closely, BUT with EXTREME CARE! Don't get any fingers or loose clothing get caught in the belt and maybe have someone with you for an emergency engine shut down. If this vibration is from the compressor, you should be able to carefully observe (or even place a stick on the body of the compressor as your assistant pushes the A/C button ON, then OFF. You may be looking at a compressor rebuild.

Worn or broken engine mounts, Something bent from a wreck and touching the engine, AC system overcharged with refrigerant all can cause a vibration with the AC on.
Any work done to the AC or previous accident damage?
What is the idle speed with the AC on? Too low of an idle speed will magnify the vibration from the AC running.

Not on any modern day car, but I've seen where the pulley didn't turn freely through 360 degrees. It had a "tightness" in one spot. Every time the pulley got to that point, it required a lot more force to turn past it.

Thanks for the response guys. Should I just take it to honda and tell them to inspect the motor mounts and ac compressor?
To answer some of the questions, car has a clean title never in accident and the vibration occurs at idle 800-900 rpms with A/C on.

A little more detail:
Is this vibration constant as long as the A/C is on and engine is at idle or does it just "stumble" a little as you turn it on then goes away as the A/C continues to run?
