Check your master cylinder. Look inside under the dash for fluid. What the hell is maping?

like the guy above said, check around for any leaks of fluid. does your master cylinder look topped up still?

if your idle is hunting around, you may have a vacuum leak somewhere. spray brake cleaner around while it's hunting (spray onto the intake manifold area). your brake booster could also be toast if you're loosing pressure badly.
