No, it was not, but the excentric shaft was out for cleaning.
Everything set up right.
The Valvetronic system is not working, till temperature of motor rise up. Intake valves are fully opening (9,2mm, with valvetronic disabled).
When engine is cold, it is operated by buterfly valve (just after MAF). It is operating also from manifold pressure sensor.
I plan to measure injectors open time, when the error happen. Will post results.
Now I wondering, if it can be oil pressure. JakuLuka wrote it was OK, when the vanos selenoid did not worked. Mailbe as oil is thick, it will do something with vanos.
I try also disconnect the selenoids for vanos.
It must be some mechanical fault as once engine runs, it work without any problem (even during cold weather).
I definitely suspend fuel pressure, as it was measured. Electric should be also OK, as the engine start at begining properly. It must be something with air supply or fuel injecting or spark timing.
