Brother, first of all congratulations for new car. Its really neat and clean car. Sorry I was unable to come online for few days. Now I am back.
Ok if your above mentioned problem is still unresolved then have a suggestion. When you Open your throatle body, there is a censor attached with it. There is a rubber ring between censore and throatle body for seal. Please change that ring, issue will resolve, only the issue which you mentioned.
NOTE: I am not an expert, so please confirm it from some one else. All the best.
