It vibrates and idle rough.I notice it alot if I'am stopped and turn the steering wheel. Is there other thing to check before I change out the idle control motor.

If your getting a iac circuit low voltage then most likely its not you iac its the circuit going to it. Do you have a multimeter to do some testing?

Lets try cleaning the iac and the passage way it sits in and go from there. Carbon build up could cause the code. Let me know what you find.
