Can anyone help me out and confirm for which is the IAC valve in my picture below, is it the black connector to the left of the orange connector at the base of the throttle body?

I'd like to clean it but first i need to know how to remove it, can anyone tell me how to remove it, does it thread out or pull out?

Need help....

1991 4.3L V6 TBI

 

....never mind. i just went online and looked up what a 1991 iac valve was for my car and found what the picture of a new one looks like. So i was right with my original thought. The IAC valve is the black plug next to the orange connector at the base of the throttle body and it just threads out with a crescent or adjustable wrench.

 

here is what it looks like for anyone else that comes searching...
