Hi Ken and Dennis,
Always learning something here.
So, I guess I was confusing two parts and thought they were the same thing.
The Idle Air Valve I still have is the part I am hoping to learn about.
The Idle Control unit apparently is gone on my van. I hope to see what that is on a future van exploration.
So, anyone out there tell me what my Idle air Valve does?
And, if anyone is up to it maybe a understanding of the Idle control Unit on the 2.1
I also have something I think is called an Idle Control uit on my 1.9 but it is currently not hooked up.
I’m interested in knowing what that does as I have a couple of good ones now at hand and could install.
