I'd go for the mass air flow sensor first! Mine went a week or so back and had issues.

Sounds like the same symptom I had on the Aldi a couple of weeks ago. Said the same thing when I scanned it.
I looked around in the engine bay first and noticed that one of the little pipes on the inlet was hanging off at one end where it had perished. replaced the pipe and "hey presto" all was well :cool:
Might not be the same problem but worth a look for nothing :wink:
