Almost like you have some kind of electrical glitch thats disturbing many components. Maybe log battery voltage when driving.

 

Well, made progress. The intermittent severe misfire under load, between shifts is resolved. That was something rather dumb/unlucky… when installing my plugs, I had used a magnetic spark plug socket. The magnet apparently broke when installing #9 and I hadn’t noticed. A part of the magnet was stuck to the top of the spark plug.

bank 2 no longer showing misfires. Bank 1 is intermittently misfiring at idle, but I am still awaiting replacement MAF sensors, as it was seen in data that bank 1 MAF voltage is unstable at idle.

as for the trans solenoid question; I’ve yet to determine if what I’m seeing is a fault…

BUT the car is currently driving quite excellent.
