Default Rough Idle? Bounces from 1,000 rpm to 1,500 rpm constantly?

I have got this problem for over 2 days and cant figure out whats wrong. I thought it was my throttle cable being too tight...but no matter how loose or how tight. It just idles @ 1,000 rpm and bounces to 1,500... CONSTANTLY. Dam its annoying!

Check all the vaccum lines. Mine did that one time because my cruise vaccum line came off the manifold.

What is the setup? Had you done some prior mods/maintenance and then this popped up?

This problem only occurs "sometimes"...well most of the time...but sometimes it just idles fine @ 1,000 rpm.

Is this only at start up or is all the time?

I posted this a while back, it might help. I just had to re-adjust this thing again. When I went to the Prothane motor mounts the car vibrates more and I guess makes the plunger back out. Here's the link...
