As said yesterday....its the MAF...a 2.2 does not consume 18Kg of air per hour at idle.

This is backed up by the inability to rev and the lean exhaust code.

Vx part number is 90530463

Alternatives here but, avoid the second hand ones

Presumably when warm - seem to recall about 25-30kg on cold/fast idle

I already know the answer, as its you, but for the sake of following proper diags, was the throttle closing (or nearly closing as its DBW) properly?

Yes, throttle position was all spot on.....and I even removed and cleaned the throttle body and breathers to be totaly sure (which were pretty gummed up)

Has to be MAF or its associated wiring then imho - I'm happy to make the assumption that the ECU is fine due to their history of reliability.

Did the same search recently for my car and came across the above. Genuine Siemens part, which I thought was good considering my local stealer had quoted me £112 the same day for the same part, (even Dick Turpin was decent enough to wear a mask when robbing his victims. this bloke had more 'front than a row of shops' and wore a badge with his name on, so I knew who was 'robbing me)
Good luck sorting out the problems. :y
