[s-cars] UrS4 hesitation problem, suggestions?

[Ira Deere]

Hello,
'93 S4 hesitation between 3 and 4K but seems most
apparent at 3800.  If you slowly roll on throttle no
hesitation.  Get into it quickly and you have
hesitation.  Once its above 4k it seems to go away but
I'm not risking a lean condition.  New parts recent,
fuel filter, OEM plugs.  Condition started yesterday
10.14.03  Car has aftermarket chip.  Thank you for
your help in advance.
Ira
