Turns the cause was valve clearances. Today we adjusted them 0.20mm at camshaft side. On some valves the gaps were 0.10mm and smaller - last time we adjusted them when head was on table. Problem solved, the idle is good now on LPG, need to clean injectors for gas to work properly but otherwise it's good. Haven't checked vacuum yet tho
