EVO engine idle vibration
OK, I'm on my 2nd EVO, and while this one doesn't have the decel/grinding noise the last one did, it does seem to idle a lot more harshly. I get a vibration I can feel thru the seat and the steering wheel that I would consider bordering on unacceptable.
What is everybody else's experience?

The Evo has very stiff engine mounts and this should be normal. It's very subjective as to what constitutes harsh vibration. This is a raw performance car. It's one of those compromises you make, along with squeeky brakes, loud cabin noise, etc..

I get it to, but it doesn't bother me. I noticed that every now and then the rpm's will dip into the 700's (watching my monitor on the SAFC). That is when it happens, it usually happens when I have the air conditioner on. Hell, I'm used to my old blown Mustang dying at idle randomly, this is 10x better

I feel lots of vibrations too when the car is idle. It almost feels like engine knocking every 3 seconds. But it rides smooth so I guess it only happens at low RPM's.

Mine only does it with the AC on. As soon as I turn the fan off, the RPM's go back to normal. Kind of annoying, but I've accepted it's a high peformance engine. Is there a fix for this? Like more powerful battery, alternator, or AC comperessor....

I wonder if your noise's' are related to mine...
-I have an MR, stage 4 which I believe and hope to be unrelated-
When idling, every so often, my engine sounds like a brokenwashing machine...An old one.
It sounds like a hydraulic issue that cycles every second, and my floor shakes like mad.
Good news, my RPMs, voltage, and temps remain uneefected, but I cannot source what it is!
Thoughts?

For the AC problem--a grounding kit will help, clean your battery terminals too--they could be corroded. You might want to bump up your idle 100rpm if its almost stalling.
