Definitely unplug the maf and see how she drives before committing to a definite maf fault (this will put the EML on though, but it should go out after a short while)! The Maf, if the same unit as the 2.2, is shared with a few vauxhall's. Including (but not limited to), the Zafira (not sure on engines but it's what my 2.2 maf was replaced with), Some astra's, some vectra B's and I believe some later corsa's. If the little metal posts inside the maf that you can see are rusted or corroded, it's most likely failed tbh!
Also if you have the single coil pack (can't remember if the 2.0 has) then check the rubber tubes that fit onto the spark plugs. These deteriorate, especially so if they have ever been immersed in oil. They then split and the coil pack can arc to the the head instead of the plugs where it should go! Top tip if the tubes are split you can clean them really well and use super glue to stick them back together. It's a good temporary fix and I know that this problem can cause reduction in power and in extreme cases stalling.
used Maf should be no more than £5 it's what I paid for mine anyway (from local breakers)
Hope this helps you in some way
