Help…New to me OBS 95 5.0

[iyoslvr]

I have a 211 code and a 332. Need to resolve the vacuum line or add in a resistor to the tad tab? Air pump in place but not connected.



Should the barb on this be open? Seems like a hose would be connected? Also screws in vacuum tree…any recommendations?

Trying to figure out what this should connect to?

Hey there Iyo
Welcome to the zone!
Wires first. The black wire in the pict goes to the capacitor. (The silver cylinder directly behind the connector in the pict.) If you look at the bottom of it, you will see the broken wire. Its there to absorb EMI (electrical noise) from the ign coil. It needs to be there.
There should be a hose connected to the port on that solenoid for sure.
It looks like the vac solenoid for egr.
That poor truck looks like its been the victim of an emission controls bandit,
Some people believe that removing all of the pollution controls will make it run better, in most cases, the opposite is true. Those egr valves and thermactor pumps work with the engine controls. Its an age old story.
Looks like the wiring took a hit as well.
Do you have to meet air care or some kind of emissions compliance to register? If it all has to work, I would recommend an engine wiring harness and vacuum harness from a
95f-150/Bronco and start fresh.
Depends on how far you want to go.
Heres a pict of the vac routing sticker that should be on the rad support or underside of the hood.

Hope this helps
Cheers!

Thanks for all the info. Looks like the wire was forcefully removed from capacitor. Looks like I need to source a replacement. I do have to meet a visual inspection and a sniff test. I think I’ll pass on the sniff but the visual looks too problematic as it currently is.

Thats a Tall 10-4
Those sort of ops require some meticulous R&R+planning to successfully accomplish the chore and even then, the blasted CEL can still get triggered.
Messing with speed density systems is akin to walking into a minefield.

I trust the holidaysare being good to all.
Been a mixed bag here, as had to go to a send-off yesterday.
The new year lurks directly ahead.

Ok 2nd question… where does this air charge temp sensor on intake connect to?

 

[L\Bronco]

Hey Iyo!
The wiring for the ACT (2wires) goes to the PCM. One wire is a 5v reference wire and the other is the Air Charge Temp sensor signal. Bot wires should be in the top engine harness. (Remove some tape/ loom, around the sensor area, they should be right there. Hope that helps!
Cheers!

Thanks for the reply. Can’t find them wires anywhere. I’ll keep looking.

As I was investigating I found this as well…..a sensor near the air filter box near the shock hoop. Where shahid go? Sorry and thanks!

They might be cut off inside the harness somewhere.
That sensor is the AIR charge temp sensor. It usually clips into the airbox or the rubber tube between the air bos and throttlebody
Hope thst helps.

10-4….it’s all becoming clear now. The intake manifold I have is a 5.8 instead of a 5.0. Granted I have a 5.0 block. Previous owner really got me scratching my head….

So I have a k&n intake with no port for that sensor on the tube.

Would the recommendation be to extend the sensor wires to the manifold sensor location? If yes then is there any difference between the threaded sensor on the 5.8 vs the plastic push in on the 5.0?

 

[L\Bronco]

Hey there Iyo,
Im a bit confused here. A 5.8 windsor intake is almost 2” wider than a 5.0 version. It physically wont fit. Can you post an underhood pict that shows the whole area? (engine bay) Then we can hopefully help you figure out what is up.
You should be able to extend that harness to the act sensor in the intake.
Hope that helps
Cheers!

I looked at the stamp on the block above starter. Stamp says it’s a 5.8 block which now makes sense why I can find wires where they should be. Seems P.O. Swapped to a 5.8 from 5.0. So that means I have a 5.0 harness and I assume PCM is for a 5.0. Not sure if I need to do anything? TwEECer j3 program or just run it as is?

But now back to the ACM sEnsor, keep as is or relocate/ extend to intake manifold location? Will that mess things if the PCM is expecting it to be in air box but now in a different spot?

Thats great actually, you have a 94 roller cam 351w (one of the most sought after ford engines out there)
Can you get a pict of the tag on the pcm connector? I can figure out what it is for you.
Cheers
