Engine Vibration at 1100rpm
#11
I'll second those who have cleaned everything and still have the vibration - it's distinct in certain conditions but I'm very observant about that kind of thing. Seems worse when cold but generally like the engine is semi-inherently unbalanced at certain rpm in some conditions. I've posted about this in the past as well, especially lower idle under higher loads (A/C, etc)

Haven't had a chance to take a closer look at all the pulleys/tensioners yet.

Did you ever figure out anything else? I wouldn't take it to a dealership, as they're typically not very good at deep-level diagnostics without simply massive remove and replacement of common components - of which it usually isn't.
