Vacuum Schematic for D-jet 1.7, ...anybody?? Options

[vesnyder]

Anybody have a legible/usable vacuum schematic for a D-jet 1.7? My hose set is not complete and need to replace and it is not clear all the hoses are connected properly.

BTW - my car is idling at ~3k+ RPM so I have some serious issues!

Slooooow down Vance. One thing at a time. This is somewhat complicated until you figure it out.


The first thing you describe I think was refered to me as a flashback valve. You should have two hoses coming from the heads on either side. IIRC the other short hose (off the top) goes to the air cleaner.

The round thing is the AAR... very important to make the D-jet run to have this plugged in correctly. You should have a connection with a short hose from the plenum (not manifold) to the AAR. This should be a short plastic / rubber Y fitting. The small connection is a thin hose that connects to the advance on your distributor. The exit connection from the AAR should go back to the intake boot.

Not really sure about your other connection you say is near the MPS.

Do you have your decel valve hooked up correctly? You can run without it but it helps if you know where all the hoses go.

Take some time and study both the 1.7 and 2.0 vacuum diagrams. That is how I figured it out.

You'll get it.
