Running lean at idle

Ok, since fixing manifold gasket and fitting a new working wideband (plx this time

)
I am running lean at idle.
rest of rev range is ok, but at idle it starts off ok and then gradually gets leaner and leaner, until it starts to sound rough.
any ideas? I am guessing MAF sensor? which i may have a spare if i can locate it.

suppose it helps if hose is actually attached to inlet plenum

Glad I'm not the only one who does these things!

nice rich cold idle that goes to 14.5 when warm...guess that is that fixed then.

For reference, the K doesn't have a MAF it has a MAP; on S1 it's built into the MEMS1.9 ECU; in S2 and VVC engines it's built into a combined pressure/inlet temperature sensor that's located on the right hand (drivers) end of the inlet manifold.
Cheers,
Robin

Yes and they are generally very reliable, I have known 1 go down so far, completely threw the running and made the engine very difficult to start.
