My 04 S60 2.4 NA Auto keeps tossing me P0171 code. The car runs great w/ no loss of power. The PCV system passes the glove test... it pulls the the rubber glove slightly into the valve cover. A quick glance under the hood shows no apparent vac leaks/ hoses off or mangled. Any thought or tips?

It's a vacuum leak. Finding it requires a diligent "VAT" inspection of all the hoses. Praise the Swedish gods it isn't a BMW which are really nasty to leak test.

Thanks for the input. Can you explain what you mean by "VAT" test?
