When my cars cold the idle goes up and down constantly. No any more than 200 rpm but its definitely noticeable. What could be causing this?

A vacuum leak would do that. Check your lower intake manifold gasket.
Notorious for going bad on these motors.

Your kidding.. All the gaskets have just been changed less than 5k miles ago. But I did have a coolant leak and a shop said it was probably my headgasket, they put stopleak in the coolant and it stoped.. This time i'm gona do the gaskets myself..
