Here is a video of cold start. The car has sat all night.
The u can hear the vanos oil pressure come up and see the afr go from 10.0 climb to 11s. U can also hear a high pitched squeal. I believe that's vanos pressure. I have heard this sound and for example and seen the afr from 14.7 drop very quickly to 11.5 when warm. Anyone expierence that sound before. ?
