Allright, so I had reset everything and did some driving...
No misfires so far but these came back:
E4 (228) O2 Sensor Controller bank 2, deviation too great, deviation rich.
E3 (227) O2 Sensor Controller bank 1, deviation too great, deviation rich.
Interesting that I had struggled to solve Lean fuel codes a little while ago and now rich fuel codes are busting my chaps.
Other things that I don't like:
Hissing sound (to be verified - may be it is normal sound of air travel trough intake, passed smoke test)
Looking trough Oil fill opening - I don't like the way cover looks inside - too dirty, I am tempted to take everything out - Intake, Valve cover, PCV, replaced all hoses where applicable and install all new gaskets and study every part under microscope, get everything sparkling clean.
Oh,and I noticed - one of the pumps was leaking, took it out, installed a little O-Ring in to the part with rubber top and net basket - no more leak at the pump but reservoir is still dripping - it was getting dark so that to be resolved at later time.
