Rough Idle
The truck is a 95 f150 4.9
Truck runs real rough at idle.
pulled codes. 411 and 213.
411 is unable to control rpm during low rpm self test
213 is spout circuit open.
I have checked the spout connector and it makes good contact.
I have a new TPS sensor,plugs, wires, set timing to 10 btdc. Have cleaned everything and found no vacuum leaks.
Ignition control module or PCM maybe?
Sorry to beg for help my first post, but I am at my wits end on this thing.
Thank you in advance for any help.

I bypassed the spout connector to make sure it was not the problem.
I get 9.5 volts with it running with the pink wire 929 on the ICM made to the pink wire on terminal 36 on the PCM. I pulled the same code 213.
Anyone know what the voltage should be?
Thank you.

So maybe the truck gods do not want me to sell my truck.
This truck has run flawlessly for 10 years until Iwant to sell it. Then the rough idle problem. Yesterday we had a bad rain storm and my kids basketball goal fell on it. It dented the roof slightly, slid down the window marking it and dented the hood. A little rubbing compound took out the marks and is going to survive.
The gods knew a little Texas hail would not hurt this truck, as it has survived many hail storms. So it went for the falling object to stop the sell.
Yes I have pulled the wires one at a time. Have not done a compression check nor do I think it is EGR problems, but I will check the EGR. The spout circuit open really has me stumped.
At a loss for what to do next.

If you have time to do some reading, this link will take you to some threads that mention spout circuit open.
spout circuit open
If the link doesn't work, go to advanced search and search for +spout +circuit +open in this forum. I got 23 hits.
One post said that if you disconnect the spout plug with the engine running it will throw that code.
Another test sorta like pulling plug wires is to start the engine cold and feel the exhaust manifolds for each cylinder as the engine heats-up. If you have some colder pipes, they are not firing as well.
I am still leaning toward a vacuum leak or egr ( same thing).

Wouldn't an EGR or vacuum leak make the engine idle higher or race? This is more of a low idle problem.
I took the plug wires off one at a time, and this may sound odd, but I could not tell a difference in the way it is running now and with each plug not firing. And keeping with the gods are angry theme, I pulled end off the #5 plug wire. Brand new and yes I did pull the boot notthe wire. Of course I thought had found the trouble, but replaced and still same problem.
The first link did not work, but I did and have read up on the spout circuit through the search feature.
Thanks for you help!!

Something else that you might want to try is pulling off the idle air bypass and soaking it down with some carb cleaner...that's how I cleaned my idle up

Thank you, I will try that.
I have been reading on the spout circuit and can not find what it does other than come from the PCM and go to the ICM. Once it gets to the ICM, what does it control?
Anyone?

a coupla summers ago, my truck was missing really bad, and rough idle too.
i pulld the plug wires one at a time, and got shocked to beat hell.
one of the wires had dried up and cracked, letting the voltage short out to the head or manifold, new wires and plugs and it ran like new.
being the cheap redneck that i am, i never checked for codes..., hell, i thought the cam was going flat, lol

well according to my manul, if voltage is present(which it was) this indicates the ICM is bad. I changed the ICM and the truck still idles rough, but the 213 spout circuit open code is now gone.
Odd thing is whan the key on test advances the timing it runs way better.
With the spout connector out I set timing to 10 btdc. Then I put the spout back in and it advances the timing to about 15 btdc. I think te book says it should be more like 20.
Im still confused.
