... that might also be a dodgy plug/wire on the connector.

Which would also explain why old mate had a spare MAF sensor.
They are pretty reliable really but, yes, they do fail.
They only need a clean about every 20 or 30 thousand K's and some never get done for 100's of thou

See how ya go, if the problem returns or is intermittent then I would be checking the plug

And some just never get done. Bloke across the road came to me saying his NAV is a bit off. I asked him if he has cleaned the MAF. He said whats that? I showed him, handed him my can of cleaner, as I don't need it now, and told him to remove it and clean it. Haven't heard back yet if it made a diff.
But yeah it could be just a dodgy wiring connection too.
