B14 idle problems

[kaarel]

Hi all

My 340 with cvt gearbox sometimes have idle problems and today it started again.
So when I was braking to stop because of red light,then engine will stop when speed will be around 0-10 km/h.
and that happened with every red light.And after starting car it wants to idle around 500 rpm.And then the eco gague will be almost in the beginning of the red line.About 3 times higher than normal idle.
And in the evening there were no problems at all.
I did that emvk blowing test,but it seems to working well.although these to hoses which go to gearbox,the one which is driver´s side(left one) there were very low air pressure(almost none).Is it bad?
Sometimes engine idle´s very well and next day has rough idle.
Somekind vacum problem?

Cheers
Kaarel

Loose carb base?

Common fault I hear.
