08 650i 02 readings and low end power issues

Overdrive138 · 02-08-2020, 03:33 PM

Hey guys i have an issue with low end grunt power loss intermittently. I Changed ivm , vanos seals, vanos cleaning, spark plugs, chked fuel pressure its at 50 psi ,fixed a few vacuum leaks etc, no misfires that im aware of . Can anyone decipher this 02 readings? Ive looked all over for fuel trim numbers but this is all i found. Seems like additive is short term? Looks to be running lean but by how much ? The pic was taken at idle. Thx

Somebody may know anyway, but just FYI this forum is for the later (2012+) 6 series. And for no reason I can even guess, there is no forum here for the 2010 and older model.
