Hi all.

Indeed Dennis' tip that those two plugs being identical and easy to mix up,
was very useful. The '85 westy I helped a friend with had those plugs mixed
up.
Not placing blame but the shop that did the major engine work likely did
this.
Easy mistake for a non vanagon shop I guess. Heck. I couldve done same
given that I don't know digijet that well. Ironically, the way the wiring
harness laid, the air regulator plug wires are shorter than the wires to
the throttle switch plug. So it would look logical to unknowingly
incorrectly install those plugs.

The bus immediately idled better but due to time constraints the owner
didn't have time to test drive the bus and I have my own bus work to do.
(Stoopid brakes)
She did however, notice it was idling better. No more surging. I suspect it
will drive ok or at least better.

Between this bus owner having to move from her 15 year long residence, and
a large bill for the engine work, she has a lot on her plate and is very
appreciative of the list help.

Great to learn a little about digijet and lend a hand. I addressed a few
other things while in there.
Ie abrasion wear at vacuum hoses AND the new hose from coolant tank cap
being too long. This hid the oil dipstick tube rather well. Upon me
removing the engine lid, the owner  immediately spied the dipstick, not in
the tube but basically just lying there, between belts and crank pulley.
The dipstick tube now has white tap wrapped around it. It won't stay white
but should help her out.

So a big thanks from her any myself. I would never had known to check those
two plugs.

FWIW, the plug for aux air regulator was a little heat damaged so if one
sees that, it's one indicator that it is or should be at regulator which is
closer to engine than the throttle switch plug.
And, the throttle switch plug has a brown-yellow stripped wire. The aux air
plug does not.
On her bus, that aux air connector housing was missing some plastic. I bail
wired it to the regulator and taped a note to the engine lid regarding that.

Neil.
