Yea your give always are the clearing adeptive and seeing short term peg + 25%. You can think of 25% as 100%, once it hits 25% it jumps to a different block in the long term table and keeps doing that until it can get to one that is rich enough to satisfy short term. S you are running extremely lean from initial base value. The reason it ran ok before is because the leak or lack of fuel came on gradually and the PCM was able to compensate, once you clear the adeptive now it is set to base map and will run like crap, same thing happens all the time to vw/Audi 1.8t and you'll find a nice little slit at the seem of the molded plastic PCV elbow. I really doubt you have a MAF issue because I'm fairly certain the PCM isn't even looking at them on initial cold start, and it definitely is not looking at the A/F sensors at initial cold start, so it should be running richer as it needs to be. So you either have a lack of fueling issue or a intake leak you aren't finding.

Did you never have a lean bank code at all?
