C5 Problems..

It does have a MAF. All fuel injected engines, as far as I'm aware do..

I can't off hand think of any modern PSA petrol engines with a MAF sensor.

I stand corrected! When did they make the jump from MAF to MAP then? I remember messing with MX5 and Saab MAFs in the past..

Some manufacturers still use MAF sensors on their petrol engines, the last petrol PSA engine i can remember working on with a MAF sensor is the 1.6 205 GTi, some of the larger petrol engined BX's & ZX's may have had them though. Not sure about the Toyota & BMW based engines that PSA use now though.
