Help! 1988 22RE EFI 4x4 - loose hoses!! - Vacuum tubing

Hello,
I just double checked twice and BOTH nipples that are attached to the manifold are sucking air (see photo 1).



OK, In my mind I have Nipples 1 and 2 on the manifold that are both sucking air but only one hose coming from VSV #3 - Hose A is connected, Hose B is NOT (See Photo)



On VSV 3 (see picture) I have hose A connected to A (on photo 4) hose B is loose. - I need to know where Hose B on VSV 3 goes (Let me know if it is Nipple 1 or 2 on the manifold) and where the extra nipple is supposed to connect to.



This truck was previously worked on by the guy who owned it and something just doesn't seem to make sense.

All photo's can be seen here.

That 3 hose nipple is manifold vacuum and lots of 22re's have one of them capped off from the factory. Not used. From what I can see A on the sensor goes the intake and B goes to the fuel pressure regulator.

the Hose a and hose b made me think of the Chitty song by Doug Moreland. "Jose and jos-b, juan and two....they're quadruplets"

I'm going to do this and see how my gas mileage / check engine light turn out.

Were you driving it with one port open? if so it will def help, that's a straight vacuum leak. It would set a code for sure.

Update

Well,
That hose is now plugged into the right side of the intake plenum and the left side is Capped. I just replaced the O2 sensor and the car runs really good with some way better gas mileage. Let me know if that intake shouldn't be Capped.

Anyway, still throwing the Error 71, EGR so Ideas are welcome.

22re's are vacuum funky. The vacuum diagrams vary greatly depending on year of engine and whether it is federal or cali spec. Is this the original engine from the truck and does it have a diagram sticker under the hood?

As far as I know the little deal with the three ports is just a three way splitter and every 22re I have ever seen had two of them pluged and the other one going to the fuel press VSV (the one at the back of valve cover).

EDIT: on second look at your pic I see three VSV's. All of the ones I have worked on are 85-87 and they only had two VSV's (#1 and #3 in your pic) . assuming the vacume diagram is correct for your truck it looks like you should have two hoses and one cap on the three way splitter, my guess is the other one goes to VSV #2.

the little cap that is missing from the other VSV is just a filter, it will work fine without it and probably will not cause a problem unless you are in really dusty or we conditions

Your EGR system doesn't use any of those VSV's, so at least that's not the problem. (if you diagram is correct for the year).

Your truck is Cali emissions compliant though, I can see the EGR temp sensor in your first picture. FYI.

For the code 71, first check the EGR valve itself. Just apply engine vacuum to the valve at idle (engine warmed up). The engine should die or at least come very close to it.

Then test the BVSV by applying vacuum to the EGR valve through the BVSV with the engine warm. The engine should die again. Try this with the engine cold and it should do nothing. The BVSV keeps the EGR from operating when the engine is cold.

If both these tests are good, then the modulator is probably bad. There are more tests for it in the FSM, so go through it if you have the manual and the tools (vacuum gauge / vacuum pump).

You can also put an ohm meter on the EGR temp sensor and see if the resistance changes with the engine at 3500 rpm and warmed up. If it changes dramatically, then the system is working. (but you wouldn't have the code if this was the case).

Yep, 3 port fitting, 1 to FPR, 1 to factory cruise control, 1 capped on my '85:

I went through the same EGR bullshit on my 94' 22RE cali spec rig.

First off, any old truck like that will occasionally get a sticking EGR valve. It would a good practice to take all of those vacuum lines off and spray cleaner into them with the engine running. They are very sensitive to sludging.

Second, replace all of your vacuum lines with either a genuine OEM vacuum line kit or wiper washer hose from Autozone. I played the game of getting something to fit and most have a pretty loose fit. This system only operates on a couple inches of vacuum so ones that are loose will bleed the very little amount of vacuum is in the line. The wiper washer requires lube to slide on they are so tight (I love saying that) and seal up well.

Third, make sure your VSV or thermo vacuum valve (which ever you have) is working. Do the resistance check on the EGR temp sensor.

The quickest way to diag I've done was T in a vacuum gauge, tape it to the windshield and drive under light and moderate load once the engine comes up to temp. If you have just a few inches of vacuum, all vacuum related components work.

Then pull back in the shop with the engine running, pull the EGR vacuum hose and put a pump on it. Pull just a couple inches on it and see if the engine stumbles. If it does, EGR works fine. Replace EGR temp sensor. If it doesn't stumble, replace valve and clean all of the usually sludged up EGR tubes as well.
