97 TS 8v: Hesitation accelerating below 2000 rpm.

I was wondering if I could get some advice as to what is possibly causing
the following problem. When accelerating at low rpms the car hesitates and
jerks (this below 2000 rpm). Took it to the local Alfa garage and was told
its probably the air flow meter. I've been researching this and could also
be the lambda sensor (despite no anomoly detected by the Analyser according
to the mechanic).... With the car stopped and not in gear it'll rev across
the whole range with no dips or hesitation, this only happens when driving
along and I accelerate at anything below 2000 rpm (doesn't always happen).

Any help or insight into this matter would be appreciated.

Thank You.

Faulty fuel pump, partially blocked fuel feed, dodgy Ht leads

I would check the plugs and leads first

The 8 valve is a bit crap under 2000rpm anyway. If you are trying to accelerate in a high gear under 2K the car will feel a bit lumpy. If it happens when moving off, that's different.
As someone said, check leads and plugs, also check the air filter isn't clogged.

Hope you sort it soon.
