Yes the AMM is out of spec ... but ...
I went back over my records and it has been this way (fluctuating between 2.6 to 3 - mostly 2.9) since 2008 when I started recording test results. So when there have been not running problems its operational specs have been "out of spec".
I'm shopping for a bone yard replacement anyway.

No - the hesitation is not gone ... it comes and goes. It is getting worse and more frequent.

I have noticing black smoke now from the exhaust while the engine was warm, starting from a stop.

I pulled plugs and the engine is definitely running rich based on the condition of the plugs.
