Hello... Thanks roland W. , martin Newiger, steve B., for yor advice. I will start fixing this the next days ... You will be informed. After removing the shield under the engine I found , on the right lower side a tube 15 x 5 cm in size with 2 plastic connectors and 2 hoses .....one is broken.. Was machen diese teil?????
Sorry At the moment I cant imagine what you are describing, but it sounds like if your engines krank case breather system is broken and the engines intake air flow has been disrupted.
Close the pipe off if you can´t repair it and then see if it makes a difference.
