Car is Messed up

OK.. PART1::when i start up my car it races to 2000rpm and then slowly drops down to 800rpm and then seems sluggish when i release the clutch. this only happens when starting up and getting to move, once moving its ok, except that sometimes when i push the clutch in between shifts the rpms go up to 2000or so? i pretty sure thats not suppose to happen. PART2::i have a short somewhere in the radio area i have installed, because when i move it like the check the wiring the accessory fuse pops( I'm Runnin low on fuses!). any help would be greatly appreciated

i had the same thing w/ the rpm's. part of the problem was a carbon build up in the throttle body, the rest was a vacuum leak. clean out the throttle body and see what that does. if that doesnt fix it, start tracing the vacuum lines and look for a leak. if you have to, take some throttle body cleaner and spray along the vacuum lines and see if the idle changes at all. if it does, theres your leak.
