[urq] 84' Audi QT

[Pasqualoni, James E]

I know this sounds silly, but with any (potential) fuel system-related
issue, particularly at this time of year, you may want to throw in a bottle
of dry gas.  There could be something (air/water) in the fuel system that is
partially blocking the line at idle.  When throttle is opened, the added
pressure pushes the impediment so that it effectively blocks fuel flow.  A
cheap way to rule these things out IMHO.

Good luck!

I don't suppose you have all your old parts with you as spares....could
start swapping them back in....

I would _make_sure_ that dizzy is properly aligned and properly tightened
down.  Double check all your ignition connections.  Not sure what sensor you
are referring to - but only thing I can think of over there is the vacuum
dealy bob for the WUR.  Make sure your vacuum lines to the WUR are okay. Can
you hook up a fuel pressure gauge and monitor at start up?  It should climb
to about 50psi within a couple minutes.  No knock sensor on WX.  Start her
up and check duty cycle, just to be sure.  Maybe there is prob with the Freq
Valve and once it goes closed loop (???whichever one is for warmed up
cars - not cold) the mixture is way off.  ????   The TDC and flywheel sensor
are generic Audi parts I think - get a used one or and swap in.  I believe
they are interchangeable - however they do need to be hooked up to the
correct harness connections...

maybe there is gunk in the tank - so it gets clogged after a few minutes -
coinciding with warm up.....

Pretty much all I can think of....

Hmmmm thinking hard here - sorry to hear you're stranded. I'm not good with
ignition stuff....C'mon guys speak up what's Todd's problem???
