Thanks Everyone!

I found aluminum oxide coating on the distributor cap,
that was stopping the bus from running well
especially at lower rpm's.
( and, surprisingly, to me, the cap isnt even 4K old? )

And that got me back on the road
to Canada and eventually home.
(and Internet access as well)

But, I am still having problems with High RPM's
running about 2K instead of 1.

I'm guessing tps too.

This is a syncro I guess I should have added.
Does this affect the location of the temp sensors?

Thanks again,
Jonathan
