420A Terrible high idle

[angryfishystick]

So I have a 1998 Mitsubishi Eclipse RS and the car idles really high like about 2200 in park and 1200 in drive.

I have replaced my mass pressure sensor, idle air control valve, my air temp sensor, and my throttle position sensor, all with no change. I also checked the throttle plate and it is closed when needed and the throttle cable is not to tight. I also tried unplugging the idle air control valve but it changed nothing.

What else can I try?
