Mystery about to be solved.

Double check leak - no leak

I use cold start VVT for both IN and OUT in the idle and cruise zone for the hot maps

Now idle and cruise lambda shows 0.996-1.004, I thought this is back to normal

Can anyone confirm if elongated timing chain can affect this? EGR or what not? No CEL for timing chain.
