Another 2.0l fault code ..grrrrrrr

[bluepain]

Had two fault codes come up the other day,both stating overfueling on tickover..
It was running a little lumpy when on tickover.
And stalled once when I came off the throttle to a halt..
Seems to run fine apart from the obvious stated faults..
These are the codes..
Got an idea of what it maybe..
But would like opinions of the good fellows on this site..

And yes is a 2.0 l
Of course it is..

Well I had to resort to Google just out of interest.
The only issue I can find that shows up on both of those codes is a leaky injector?

Too rich on both banks 1 & 2. Disconnect the MAF and see if it runs better.

Check for vacuum air leaks split or holed rubber pipes, high fuel trims and bad idle usually the symptoms

The N46 has only 1 bank mate

Will a cracked rubber seal on the fuel filler cap give a air leak great enough to give a vacuum leak.
I currently cant find any cracks on my hoses.

my best action may be a smoke test to find it.
