Can anyone please  help me with the correct  part number for the air flow meter fitted to a 2004 3lt v6 petrol number as running very rough at low revs only and may have had wrong part fitted in past.

Before you invest in a new one - I had a similar problem last year and didn't have a clue what was causing it, but I cleaned inside the intake and the MAF with Methylated spirit on a cloth. It made a fantastic difference. That said, I dont know if there are any reasons that I shouldn't have done it, as I've never heard of anybody attempting to clean a MAF sensor before. Perhaps theres a reason.

Have a read of this thread which involves replacing a MAF in a V6, although it didn't turn out to be the cause of his problem in the end (In fact, Bago may have a spare one that he moight sell). Sorry its a bit long-winded.

Thanks for that. I will try it. However I think the maf may be damaged as also have a gas system fitted which when I used to run it on gas it would occasionally back fire through the air intake at lower revs only. Only running on petrol at the mo as no one seems to be able to help on that one either.

We went through all this on that other thread. Is seems that many of the numbers are different. Anyway, if it helps, mine is labelled:

338     1629
                     K
E5T06071

Apparently new MAFs are very expensive.

As regards the backfiring on gas, check that all your plugs and leads are in A1 condition. There is a vast amount of mixed gas in that inlet manifold and if there are any stray sparks about the gas will have them! Also check the grounding cable is connected directly to the manifold. It should be at the back of the manifold to the nearside.
