I have tried looking but cannot see any fittings that look like a vacuum hose fitting?

SJBIFR,
I had same error codes (fuel adaptation limit) a few times last month. At first I thought vacuum leaking and tried to search around everywhere with no success. Finally, I changed the air filter and spark plugs and it does not come back for a month. Try this if you don't find any leak. I have 2003 3.0 62K miles.
