I am finding out that no it can not. I am not sure of this as I am not setting an iac code at all. I haven't pulled the iac out either to see if its moving. I do have vacuum like the brake booster and the map, running off of the iac distribution block, I am not sure if this is affecting anything or not.The Dark Side of Will wrote:
If you block the throttles, can your idle air system control the idle?
When I pull the 3/8th rubber line off of the iac, one would think the idle would kick way up because there is a large vacuum leak. I am finding this not to be the case. The idle barely changes if at all.
Here is the routing. its the remote iac, to a 3/8ths line, to a small distribution block. I have 1 port on the block going to the brake booster, one to the map sensor, then 2 are coming out that are feeding the two banks. So essentially one line out of the distribution block feeds the trunk side, and one feeds the firewall side. They are T'd off to feed the 3 cylinders on each side. I am using 3/16th line to feed each cylinder. I don't think this is too small however, I would imagine the iac can open enough to keep the thing running.
Maybe the distribution block is the choke point? Not sure.
