I got in my car to drive it and the idle was really rough. There was a lot of vibration. It acted like it wanted to die If I didn't give it gas. I turned it off and started it up again and it did the same thing. Any Ideas?

Check the connections on your injectors. I had a similary problem and was getting almost no fuel to one of my cylinders.

Vacuum Leak.

is there improvement after it warms up?

Sounds like a hose or connection cracked or came off somewhere. Check around the intake manifold, IC pipes, etc

if you suspect a vac. leak a can of carb-cleaner can be useful, but BE CAREFUL.

Thanks guys. I found the prob. The screw that goes into the top of the throttle body worked itself out. Luckily I found laying on the top of the engine.

That's the idle-speed adjuster. They tend to work themselves loose. Replace that O-ring on it before you re-install. Might also be a good idea to Locktite it in place and cover up the top with silicone.
