ok I can provide a lil help but alot of guys would say use the search fucntion because this is a question we get asked alot. I'm going to assume your car is stock because you didn't say otherwise. On your intake pipe there is an accordian looking piece check that for leaks first then work your way through the rest of your intake piping for leaks. Irratic idle issue is notorious with stock intake pipe. If you find no leaks post up again and we can go from there.

Spray some throttlebody cleaner around with the engine running. If the idle jumps up, there's a vacuum leak wherever the cleaner entered.
