My IAC went out. I replaced it and after doing so. The vehicle started to idle high. It idle's between 1500 to 2000. I thought the part I got from auto zone might be bad. So I took it back and replaced it again with the battery unplugged. It still idled high. Then I replaced the TPS. I could not find any vacuum leaks. I am completely lost on what it could be. Any help would be appreciated.

if you replace an IAC you normally have to drive the car for it to reset. try cleaning throttle plate on both sides with choke cleaner as well.
