Converse hr 16 engine idling for 4 minutes in the morning is normal.

Hello. The throttle is dirty. Just wash it. When starting tomorrow morning, try to add more oil. If it doesn't shake, clean the throttle. If you still shake. The throttle valve and the fuel injector are cleaned together. I hope my answer can help you. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
