Legacy 3.0r running rich

[milu]

In case anyone hasn’t seen last weeks SOTW.
I bought a 3.0 saloon. 05 reg.
it’s had a new exhaust fitted with the third cat removed.
Every thing seems fine apart from smelling a bit like running rich.
No soot.
I thought it was the missing cat but sm not really sure because I don’t think the third cat does much
Would anything in particular cause rich running?
Or at least the smell of??

Smells rich all the time
I don't know before the exhaust because I've only just bought it. Any I'll check for leaks at the weekend
Cheers

That's what I thought. But no joy.

Thanks for the info. Would failed lambda sensors show up on a OBD check?
I've read somewhere about the idle re learn so I can defo do that.
Car drives great so this would be nice to eradicate
