autozone.com has information and procedures for repair and adjusting stuff on cars... just put your year and model in.

Have a look where the accelerator cable goes on and underneath that there is a screw with a locknut loosen the locknut and screw out the screw a small bit.

haha.. haven't seen this one come up for a while. Here's a pic I always used before. You're basically looking for the round rubber cover, take it off and that's where the idle screw is (danbarr6, not sure WTF you're talking about. ) can't remember which was is which, but turning the screw one way will increase the idle and going the other way will decrease it.

Hey Ren,
Good Save.

your always a great help!!

PS Is it safe to adjust this? I read somewhere that once you change it you will never get the timing back or some shit likethat. Is it true? and what would that do to my car/engine lol (yes im a noob but hey, first car, I think I chose the right one:P )

no effect to timing
