maybe you blown a head gasket. That's what happened to me and i'm experiencing the same problem you having. It can be many other things. Like your vac source is leaking. Check all your Vac lines. It can be leaking. check MAP sensor. ETC....

check the BISS. on the top of the TB there will be a screw going into it (possibly with a cap on it) that adjusts your throttle at idle...maybe the screw came loose (or out, i've heard of that happening) which will wreck your idle.
