Engine vibration at 2k rpm

[kenamond]

I've recently noticed that my motor seems to have more vibration at 2k rpm in neutral (parked). I just completely totalled my brain by reading BS threads for the past hour, but I'm not sure if I have any good ideas about a source.

From what I read, each BS handles vibrations at a different RPM range. Could it be that the front BS belt broke? Does the front BS cancel lower-rpm vibration (maybe most effective at say - 2000rpm)?

Motor mounts?

Shocks?

?

My timing belt was replaced at around 70k , and I'm at 80k now, but I doubt they replaced the front BS belt (this was before my dsmtuners days, so I didn't know any better).

Thanks in advance!

I would check balance shaft belt immidiately. You don't need that getting caught in your timing belt. Also check the motor mounts visually to see if they are ripped or torn.
