any one know any possible causes for vibrations coming from my engine... they are not really bad but they are noticable and they are the worst at around 2500... any ideas?

CHeck your motor mounts! Mine busted a while ago. When I went to fix them, I found the broken bolts to be not even finger tight!

i'll do that, is that just a tip or were you having the same problem?

I had that same problem as you discribed. But I only found the solution after the pressure of the motor leaning on the loose bolts too long.

I just thru this out there, so you might have another idea to look at. ONce it breaks, its a pain to fix.
