ust got a 2000 corsa envoy 1.2 for £60 it's done 60000 miles and ticks over nicely but when I hit the throttle it starts to cut out
Checked air which is fine but not sure how to check fuel or anything else
Any help is much appreciated

Could be fuel supply which would explain a lack of power under load but it shouldn't make it cut out. I would think you have a rich condition detected and its trimming the fuel down to lean it out which is what's killing it. Normally lambda report which will give you that.
Is the idle steady?

Could it be over fueling if the injectors are seized

Over fuel wouldn't cause it to cut out, plus it wouldn't affect all chambers.
Normally be present as a misfire if it was that. Unless you suspect all of them at the same time.

If I quickly tap the throttle it kicks into life but when I stop and put foot down it really struggles and nearly cuts out
The air intake is fine so must be fuel issue
Can injectors be cleaned
Thanks

Unplug the AFM and see if it's any better.
