problem:

well about a week or two ago my ago my car would sputter at crusing speed. it would idle fine and run fine wot...(wtf?) so i have been trying to locate the problem ever since it started messing up. well i go to start the car up two days ago after changing my spark plug wires, and front and rear brakes and it the idle went all the way to 4k...(wtf?x2). i shut it off and turn it back on, the same thing. i checked for vacuum leaks i checked my injectors, i checked my iav. what else could it be?

thanks in advance for input
