Good
Either you fixed a leak or the ECU was border-line adapting.
Anyway , you are now running proper base line , BUT, you now have to watch to see if the adaptations start to creep up again..That will mean you still have a leak and if it is large enough, the adap will not be able to handle it.
The suspect I have would be a purge valve . You may want to take the lines off of it and squirt some WD40 in there..that will clean it and stop it from sticking.. I would do that regardless now. Just cuz they get crapped up .
Keep an eye on codes , even if you do not have a CE, as you may catch one before a bunch start coming up.. Just monitor it for a while..as you now have the tool.
Another thing I would do is get on the gas up a few hills , [dropping down to 3rd gear to keep the rpms up and so you don't get busted for speeding.]
That will clean up the 02 sensor a bit..
Lastly, I have had some luck with these new MAF sensors cleaners ..easy enough to do and can't hurt to give it a quick squirt [ CRC MAF cleaner]
The MAF is detrimental to all these a/f mix adaptations.........
