Is you talking in text speak or what??????? are you a teenager????

 

 

 

The issue you have is most likely caused by basic engine set up or a failed auxillary air valve.

 

Basic tick over speed is perhaps too low and the aav struggling to recover in time when the throttle is shut quickly.

 

With the yellow pug disconnected from the aav (back of engine battery side) see what the tickover speed is and if required raise it slightly by adjusting the base idle screw on the side of the same uinit (facing the battery) anti-clock wise is to raise the revs and clock wise to lower th base idle speed, then plug the yellow pug back in and it should settle down, if the issue is still there its likely the aav is faulty.

No worries, only playing with you, always impressed with anyone who can speak/ write in more than one language we are generally quite lazy in this country about learing other languages.
