Hi, guys.

I definitely have the vacuum leak somewhere is pcv system which cause high LTFT values 15-20%, when i block pcv hoses then LTFT becomes zero and hissing gone, but when they are normally connected im hearing the air passing through and car drives badly, please HELP!!!

How pcv channels are going in to the engine? where can they get additional air(leak)?

Hoses and all rubber are new...
