Not sure that hesitant is spelt correctly ?
The Corsa still is slightly hesistant sometimes
whilst moving away, usually in second gear.
It feels like a " flat spot " and then it smooths
out ok. The engine has just been rebuilt and
there's no plug fouling, it doesn't do it all the
time. The engine management lights occasionally
to but soon goes off, I understand the ECU stores
these faults ? How many does it store I wonder,
before the engine was stripped it was doing a
litre of oil a week ! Do you think the ECU still
" remembers " this problem and needs to be re-set ?
Any help would be most welcome, regards de Wessy.

When my corsa used to hesitate (X12XE) it was the air flow mass meter.

Just done the " paper clip " test.
Reveals error 13, which is the
oxygen sensor. How much are them
then ? Wessy

Mine's doin the same from what I can gather, is also a C12NZ... The Lambda sensor needs replacing (i.e. that thing that sticks outta the manifold).

Can get OEM vaux sensors for about 40 quid from motor factors, try Leicester Motor Factors. Failin that, can also get NGK replacements, have the code for the right one, will try and post it up when I find it again...
