[V8] Help Diagnosing V8 Fuel Problem...

[Korn, Bob]

Thought that at first, it's been at or below freezing for the last couple
weeks as well.  All gas has been from the local Amoco(BP), 92 Oct.  Did dump
some Techron in the last fill in case of some bad gas.  Am in the process of
running this tank out. 

Thanks for the thought.

Bob

I had problems like what you describe with my old '80 4k...  It was on our
honeymoon crossing the Canadian border.  Ah what a memorable moment in Audi
ownership history...

It turns out I just had some bad gas (pardon me).  It finally cleared up on
it's own after a tank or 2.  I think I changed the fuel filter when I got
home to be on the safe side.

Did you fill up in any Podunk towns recently?  Just a thought...  

Is it isopropyl alcohol that is supposed to 'dry' out any moisture out of
your tank?  Can't remember for sure, or if this is even a possibility for
your symptoms.

Happy troubleshooting,

- Jeremy

This car's symptoms are a little different than you describe.  It absolutely

will not accelerate or go up hills, constant speeds like on a highway pose 
no problem.   This is also not subtle at all, it's very apparent, like
one 
whole bank has stopped firing.  If it occurs when attempting to accelerate 
fast from a dead stop, the car will barely move...it would probably take 30 
seconds to hit 15 mph.  Also, it won't fix itself until you let the car come

down to idle for a second or two.  Once it's "broke" it stays broke until 
you let off the gas completely and the engine returns to idle.

If you aren't getting any codes, then vagcom won't help you more. Vagcom 
can tell you why the code happened (short to ground, short to +12, open 
circuit, etc...) which is pretty darn handy IF you have codes ;)   The
other 
nifty thing about vacom is you can monitor some of the car's vitals in real 
time under the basic engine settings section.  Section D2-70 thru -90 of

bentley is needed to know what you're looking at.
