Help! Can't figure out lean codes.

No CEL today! One more day and I will celebrate.

No CEL again. I think I got it whipped. Gas tank vent hose was the offending problem. Sucking fresh air into the charcoal canister and purging it back into the intake will cause lean codes.
I can't relay on here how relieved I am to have found the problem. Drinking Guinness black Lager to celebrate.

Good to hear!

Where did you find a replacement? Mine is snapped off too, and CEL is on. Can it be drilled/tapped for hose barb?

My fitting was still intact. The hose was just off of it. I just pushed it back on and it snapped in place.

Lucky you!

I believe the fitting is pressure sensitive. It is not just a plain vent if that helps. Maybe rob one off a tank in the junk yard.
