low idle, bad vibration

OK I think my idle is on the low end. At a stop she shakes pretty bad until I level out the throttle. I'm pretty sure I already have to replace my fast idle valve. Could this be the problem or should I be looking for something else?

Have you completed the steps suggested in the manual to set the idle properly? I'd start there. The idle itself might just be set low.

Not yet. I read in the manual that it most likely is a sign of some other problem and I didn't want to just raise the idle without addressing it.

Did this problem just show up, or was something else changed?

The fast idle valve could be causing problems. It might be stuck in one position. Do you get a bouncing idle as well?
