Ive been chasing down these two codes I get on startup. It causes me to run lean despite changing all 4 o2 sensors and fuel injectors. My fuel seems fine and my spark plugs are practically new. Ive also tried to clean my TMAP And MAP sensors. I am currently on stock but I am running a 3.5 TMAP sensor.

If you are getting these codes first start with cleaning the 2 Vanos solenoids. If the problem still persists, replace your throttle body.

so, actually I had this same problem. I fixed it by changing my intake manifold gasket. Try that first, it will probably solve all your issues.
