[s-cars] UrS4 hesitation problem, suggestions?

[Bjørn Ødegård]

Or did you clean the engine in the process? There shouldn't be much
moisture under the ignition cover before it misfires!
Apart from that, the 'old plugs' and 'new O2' way seems like a good
option..

Ira,

If you still have the old plugs, reinstall them. Sometimes, new plugs
are faulty. If you have no hesitation at WOT, outside the 3000-4000rpm
range, it may be a weak POS. I would start with the old plugs, then the
O2 sensor, as suggested and keep the most expensive POS as the last
option.



Vincent.

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
