Should be lots of info. Evap system problems are a somewhat common issue here on the forum.
I think the tank vent valve is the one mentioned on the video that causes the hard start problem after refill.

I had a porsche tech look at the car, what he told me is that the actual values are not indicative of a vacuum leak, rather he believes that the 6+ degree camshaft deviation on bank 2 is what is causing my rough idle, as I replaced the variocam actuator on bank 1 but I did not touch bank 2, leading to 0% bank 1 deviation and 6.4% bank 2 deviation. which I suppose is quite an imbalance in the engine timing. I think at this point the wise decision would be, drop the engine. replace bank 1 and 2 variocam plastic things and solenoids. re time the engine from scratch. preventative ims and rms replacement and trans fluid, and then put the car back together. does this diagnosis make sense?
