Hi,

I have a 1991 Westfalia with a GoWesty 2.3 engine.

It fires and runs if I give it a lot of gas (2000+ rpm), but won't idle
or even drive.  It's running VERY rich based on the smell of the exhaust.

Last night I did an oil change, topped up the coolant and it ran perfectly.

The only thing I did this morning was to troubleshoot some trailer
wiring by opening up the "Wire distribution box" and checking the
connections there.

There is a Grey/White wire that is not connected to anything and
according to the Bentlwy (97.205, connection T1m and T1N) it should be
connected to something, specially since it says it goes to the Digifant
Control Unit.

My "gut" says it's something inside the "Wire Distribution Box" because
that's the only place I messed around since it was last running.

I have checked the AFM connection, disconnected the O2 sensor, made sure
I could hear the high and low limit switches on the throttle body.

I am so at a loss and depressed right now...  I'm still working through
the Bently wiring diagram, but does anyone have any insight of what
might be the issue?

Like I said earlier, the biggest clue is that (it smells like) it is
running very rich.

Thanks,
Steve Williams
