Refer to this vacuum diagram, is it the solenoid valve you are taking about?
Is this what it looks like? If so, that is the EGR Vacuum Solenoid.
Are you getting any codes P0403 EGR Solenoid Circuit Malfunction?
Here are the 5.8 component locations, click here.
Sorry, I was napping.
Ok, can you tell what it is called now?
I didnt see any part number on it
I thought that that should be hooked to the air pump untill I read this.
Managed Thermactor® Air System > OperationOperationThe MTA system is used to inject fresh air into the exhaust manifolds or catalytic converters via an air control valve. Under some operating conditions, the air can be dumped back into the atmosphere via an air bypass valve. On some applications the two valves are combined into one unit. The air bypass valve can be either the normally closed type, when the valves are separate, or the normally open type, when the valves are combined.
Ok, it has to be one of these, click here.
It looks more like the first or third one, but they both look the same, the Managed Air Thermactor.
Do the hoses on the backside go to the exhaust manifold and catalytic converter?
I think this one is it, the one without threads and Hose nipple on both ends.http://www.autozone.com/autozone/parts/1996-Ford-F250-3-4-ton-P-U-2WD/Air-Pump-Check-Valve/_/N-j5mxjZ93xps?filterByKeyWord=valve&fromString=search

That is most likely the cause of the misses, spits and sputters.
The OBD Diagnostic Link Connector is located in the front seating area, on the passenger side, under the dash, above the kick panel, mounted at the rear of the glove compartment.
You can look up the meaning of the codes here, http://www.actron.com/code_lookup.php
so do you have any idea where this hose should be located and how do you test for codes useing the malfunction lamp my computer for some reason wont open the link
That link is a *.doc, it opens with Microsoft's word or office. You could download their free word viewer here, http://office.microsoft.com/en-us/downloads/CD001022584.aspx
I think the diverter is actually the thing behind it. Not to mention the diverter's are solenoids. They would have wires to it. Where does this hose go in this pic?
what I found out so far is that the air coming out of the front of this assembly increases when you accelarate. This is some kind of smog system right? A guy that I talked to about seems to think that hose that you are asking about is suppost to go on that port and that something else is suppost to go there. that hose runs onto a port located under the oil cap then goes to the air filter. what do you think?
Smog pump, A.I.R. Pump is the same thing. Although that part is not th smog pump, the smog pump is a pump driven by a belt. It's probably part of the smog (a.i.r.) system but not the pump.
Anyhow, you pictures are not showing up. How did you upload them?
Is this a 4 bbl carburetor engine?
If so, it appears there are 2 air(smog) pumps, do you have 2 pumps?
I still think it is a check valve for the A.I.R. (smog) pump system, but it figures the picture that I need from the Chilton manual is not too good of a picture (diagram).
If only you could tell me exactly where those 2 hoses go I marked in red, I may be able to tell what that is.
Ok, just wanted to make sure of the year and engine. 1996 5.8
There has got to be something there without a hose connected to it. Can you take some pictures looking from the rear to the front where that second air pump might have been?
that last one is a sticker that is located on top of the assembly I wondered if it was a part number or something
It appears that is a Air Management / Diverter Valve. I found alot of them here but none on page 1 that matches that part number. Am looking at page 2 now.
Here is the Chilton section on Secondary Air Injection Systems, click here. Now you said those 2 hoses that go around the rear of the engine go to the smog pump and most likely the exhaust manifold on the other side, that means that this side with the hose off must go to the exhaust manifold on this bank. In that one picture you just sent, the next to the last one, this one
Those black pipes look like they go to the exhaust manifold. Do you see an opening for the hose?
At figure 17 it has an AIRD Valve Without Pressure Relief, that has got to be it. So, that is supposed to have air coming out.
That big thing I believe is a check valve. Now the end that is open without a hose goes to either the catalytic converter or the exhaust manifold. So depending on where that other one went it would be the opposite, cause after the check valve it splits and feeds both banks of the exhaust manifold or both catalytic converters.
that what you have in the picture listed as inlet is the same pipe that wraps around the motor in the other picture and goes down to the air pump not the exhaust maniford. The picture that you are looking at there is a pipe that goes down to the air pump and a flat piece of metel that coonects to it to support it. its not a pipe. the other one that you have listed as outlet A is the one that wraps around the back of the motor and drops down. I looked at the converters and there is no pipe that I seen hooked up to them. I am thinking that the pipe that drops down the motor may hook up to the exhaust manifold.I can see one at least one of them a pipe that hooks upto it coming possibly from that area. One thing that might have happened is the exhaust was replaced and they left it off when they changed it. I am just guessing about that.
you said that this could cause the spitting and sputtering at 45-50mph. since you are sure that they are both suppost to hook up to the exhaust. couldnt I just split off the one you have listed as outlet a and connect them together?
Yes, inlet means air coming in from the air pump. The outlets go to the exhaust manifolds or catalytic converters. I saw what I thought was the pipes on the exhaust manifold.
They have both pipes here, http://www.compnine.com/index.php?pa=1&ta=1&acdmodelida=1365690727&yeara=1996&acdmakeida=1000054420&acdlineida=21&yearid=1000375613
