Well I rewired the ETA and removed the EGR while I was at it.
Now I can't find the place to reconnect a vacuum hose end.

The EGR vacumm line goes where? I have a place right in front of the engine that has other connections to it. I'm not sure if it goes there or the other vac line that I have disconnected goes there.

The other hose that I removed was the one that is into the intake manifold at one end behind the ETA wiring harness connector but I can't remember where the other end goes?
I don't want to cross these two vac lines.

The line from the egr goes back to the switch-over-valve [ in front of engine, under plastic cover]
The line from the engine goes to the input of the SOV's This is a common vac supply line for both SOVs [ one sov for egr and one sov for AIR pump, they are stacked up on top of each other]

Thanks Arthur, I connected the EGR line to the SOV, I can't find the tittie for the vacum line that comes from the ETA area on the manifold. I'll be dam>>>

Follow the vac line from the fuel pressure regulator down to the maniflod....it is right next to that line
It has a blue plastic check valve there ..it goes on top of the check valve
[unless you brok it off...]

I found exactly what you have described, the line I am not able to find the correct nipple for is the other vac line that comes of the intake manifold, there are 3 lines that come out of the manifold, 2 from one nipple, one goes to the VOP and the other to the fuel control. The other line from the intake is a lonely line that goes to ??? it is a connected to the manifold directly behind the ETA connector bracket a little farther away from the engine than the other 2 lines.
I don't know why I removed it, it probably goes to the door locks or something.

well....u lost me there ...
There is no vac line that goes to the OVP..The OVP is an electrical protection circuit and uses/monitors NO vac

Anyway............
the vac lines at the intake are
1 line from the vac monitor diagnostic sensor [on left fender well]
1 line from the Fuel reg , and one from the SOVs for the egr and Air pump.
The line from the fuel reg goes to the same check valve as the sovs do , but it goes to the bottom [ engine side ] of the check valve so that it reads engine vac under all running conditions/loads.
But the sov line goes to the top of the same check valve . This is so the sovs can not interfer with the fuel pressure reg readings
and the vac is checked via the valve.

Need more info

Arthur, thank you fpr your patience. I read my post and I couldn't understand it either. OVP hahaha.
I did edit the post and now that I read yours it makes sense, the line I removed has to go towards the fender well.

problem solved, The line went to the fender and total vacumm sensor. Now I will test drive the car with the repaired ETA.
Hopefully I don't get the Limp Home Mode.

OK
That is the diagnostic vac sensor, so you should be all set , except you may get a CE light pop up from the running without the sensor line hooked up.
If that happens , simply clear the codes and you will be back to normal..

Great help Arthur, really appreciate it. Great Forum.
