replacing the fuel rail pressure sensor on the lower fuel rail seems to have fixed it. involved process...was without the car for a while...took a lot of troubleshooting.
My '19 had a similar issue, to the point that it was stalling at idle. First it was the fuel pump/sending unit that was diagnosed as bad; this was replaced but did not fix it. Return visit resulted in replacement of a failed fuel rail pressure sensor. So far so good. Car has a little over 5k...
update if anyone is interested.
initial diagnosis was a malfunctioning fuel pump/sending unit. This was replaced but did not fix the problem. Car is back in the shop, now diagnosed with a bad fuel rail pressure sensor. Shop said this likely caused the fuel pump to fail but was not detected on...
Mine doesn't surge, it stalls. It just started doing this...4700 miles on car, no mods, recently serviced. No codes or CEL. Voltage is all over the place; I suspect this may be a contributing factor. Car going in to dealer tomorrow.

My OTD price was $34,751 after discounts/rebates; MSRP was $40,730. I considered a 301A car (OW/Dk Ceramic) with the exhaust and 3.55s for $400 more but the color and option packages on the VB just appealed more to me. If I decide I want the big screen I'll retrofit it later. Yes the small...
you can hear the additional interior locks activating from the outside after you lock the car. I have not messed around inside the car to see how the locks actually work, as I don't want to set off the motion sensors. It has a setting for perimeter sensors only or all sensors in the setup menu...
