Thanks in advance for te help on this one. 1990 Audi 90 5cyl. non Quattro n=
on tubo 10v.  I took the warnings of the improper oil filter to heart and d=
ecided to finally switch to the Moile 1 5W30 oil and a Wix filter (with che=
ck valve) and a new air filter.  Of course the oil and air filter went in w=
ithout too much trouble, gotta love that air filter compartment!

While in that area I decided to also try to tackle the ISV valve - or what =
I thought was the ISV valve.  This is where I should start asking questions=
.  The valve on top of the air box is the air flow meter - does not appear =
to have an electrical connection but it does accept fuel.  Moved on to a so=
lenoid valve located between the port and the intake. Two vacuum hoses and =
a wire connector - very corroded.  No part number on it.  I decide to clean=
 it with carb cleaner and use a vacuum tester.  Pumped to 100 PSI lost all =
pressure within 2 seconds.

The apparent part  number is 034-906-283E.

I put everything back together except the crankcase ventilation tube (it wa=
s collapsed) and went to start the car.  It had a hard time with idle.  Con=
cerned the fuel delivery system had lost some prime I took it out for a 2 m=
ile hard drive.  Response was perfect on throttle, auto trans shifting flaw=
lessly.  Brought it back and it idled at below 1000RPM for the first time i=
n 2 months.  Running smooth and idled without any problems until I shut it =
off and let it sit an hour -now it acts as if it is not getting fuel at all=
 - all cylinders are producing spark new fuel pump humming along.

Tried capping off the solenoid valve mentioned above but still no start.  T=
oo darn cold to have these problems.  I know the problem has to be a simple=
 one :-P.   Thought I would throw this one out here and see if anyone had a=
ny technical advice of if I should send this one to the Audi Gods for resol=
ution.
