clean your throttle valve out with carb cleaner
I suspect it maybe a lambda issue for some reason but do the above first but don't move throttle plate with your fingers as you can damage the spring in mechanism (no cable fly by wire)

 

Thanks, i have done it before that... Removed the plastic house also, checked the gear at the throttle and the resistor paths, cleaned with electric spray.

 

not the electrical bit:wow: the inside of throttle housing

 

I wrote 'also', i have cleaned with carb cleaner the airways throught the trottle valve, removed dirty oil residues, can't do more in cleaning i believe

 

ok ,cant see "also" in your post ....I would get your ecu codes read but I would also check you have no splits in your induction hose from maf sensor to throttle valve ,take it off and check properly ,also check you have no leaks on your breather pipes also

 

I have changed rubber lines between maf and throttle body, that is ok. There is no ecu error code (no mil also). What is strange at the head when i put my finger to the breather hole that sucks it, i thought theres gonna be pressurized air! Is that normal?
Im speaking about on idle only.

 

upload a pic where ..should be no leaks ...
