[V6-12v] Hesitation

[James4ihl at aol.com]

Hi All --

Regarding the hesitation problem I've asked about in previous posts:

I've cleaned the MAF sensor. It's made the running better in other respects, 
but hasn't cured the hesitation problem. I checked the vaccum system around 
the intake manifold for joins/kinks/leaks and didn't find anything obvious. The 
car is booked in to the garage to have it's fuel delivery/tank checked (but as 
I mentioned before, the problem pre-dates a new pump/filter which weren't 
blocked when removed, so I'm a little dubious the problem lies there).

Any other ideas from anyone?

FYI - 1992 UK model A80 V6 2.8L, Manual, No EGR, Manual CO adjustment via MAF 
sensor on this model (so no adaptation cycle on O2 sensors)...

Cheers,
James
