I know this topic has been beat up. But I need help cuz I'm not familiar wit bmw's
09 328xi N51 both banks lean and my upstream 02 sensors are reading 2.00 volts at idle now I know that can't be right.

New Parts installed
Valve cover
Hose from valve cover to intake
All 6 ngk spark plugs
All 6 Delphi coil packs
Cleaned maf
I bought a cheap smoke machine from Amazon and all it does is blow my smoke boot out my intake so either I bought a pos or I don't have a vacuum leak.

Car runs great other then it stalls twice in the morning since it's got cold and the fuel mileage is like 9-10 mpg.
Also there's a screenshot of my smooth-running values which I know nothing about.

Please someone tell me something that I can move on to next
Is it the upstream o2 sensors or do u think it's a vacuum leak?

I need to get this fixed before my Catalytic converters and those are not cheap
Thank u

Here are some screenshots from my ThinkDiag bt scanner
