Well, I have gotten the idle speed problem worked out pretty well (idle
switch adjustment, oxy sensor, vacume leak)  Now I'd like to try for ignition
timing. I checked Bentley, and it indicates some VW tool.  Can anyone walk me
through timing a digijet engine with a timing light and nothing else?  I have
a timing light, but have never really used it.

I assume:
Pull idle stabilizer plugs and plug together
Pull distributor vacume lines
Clamp induction wire on spark plug lead (which one)
Shine on pulley.  What do I look for here?  What are the degrees, and how do
I measure?
How do I measure timing advance?

Please help.

Also, I never got any response about the power steering idle boost switch.  I
know one wire goes to the boost switch at front right of engine compartment.
Where does the other one come from?  Someone with an '85  with p/s please
help.

Thanks again,
Peter
