Poor running 3B

[PeterBergin at aol.com]

I did loosen a line at the filter, gas squirted out.  Just can't  
understand why it would not be the MAF if the condition is the same when I  unplug 
the harness from it.
Thanks, Pete

Hi  Pete,

I had a similar condition with a non-Audi, figured I'd pass the  info 
along. 
I haven't followed the thread closely so maybe this was  already covered. 
Anyway the car was (still is) a Volvo with a Ford engine  transplanted, so 
everything is suspect.  I found that I could idle up  a hill (very light 
throttle actually) that I could not drive up  accelerating normally.  The 
culprit was the main fuel pump (there is  also an in-tank pump).  I 
replaced 
it with a known good used pump  ($10), still going strong.

HTH,
