Check your EGR Valve and your breather pipes to camshaft casing. Both are easily cleaned and easy to take off. However, you need an EGR valve gasket set, which is only a tenner or so from Vauxhall garage. Also, I would get yourself an OPCOM reader from eBay as you'll be able to find the fault code and perhaps save yourself some money, as several problems can bring on the EML.

id say get yourself to a garage have a diagnostics done, might cost bought £20 find out the problem and change it, if its egr valve get a good one from the scrappy as main dealer will break the bank :S from my experience may also be MAF sensor, picked my MAF sensor up new for bout £40. but if you can, get on diagnostics first :)
