i drive a W reg corsa 1.0L 12v (shocking engine i know ) but for the last few weeks, every now and again, when im accelerate from low revs, theres a loss of power for about a second or so (like as if ide taken my foot off the accelerator), then all of a sudden the acceleration comes back.
it just did it a few times on the way home now, and the engine management light flashed on, its off now. anyone know what the problem could be?
any help appreciated, cheers, chris.

not 2 sure, could be loss of compression. Mite hav 2 get pressure test for cylinder head. My head gasket blew a little while after the problem your experiencing. Is the coolant level stable and is there and oil leaks?
could also be your AFM (Air Flow meter) or a dodgy airbox

my mates did this, could be either:
lambda sensor
crank sensor
EGR valve
he had them changed and it was fine

hmm well apart from the list of things mattk said, the only thing I can think of is loss of compression. A compression test on your cylinder head will tell you if thats playing up 
p.s. BTW is there lots of pressure inside ur coolant tank?

if the light has stayed on for about 10 seconds do the paper clip test and see what codes are stored in the ecu, even though the light isn't on now it should have stored the code if it was on 10 secs or more

AFM i recon
never done a paper clip test, but with tech 2 you often get
o2 sensor low voltage - which is also a mass air flow meter fault
fault i may add iv also got one for sale!

sounds like it is, normaly you drive along, go to accerate (floor it) and it like bogs down and the eml come on
do the paper clip test then
