Bought it couple days age it’s been running fine I’m still trying to get into driving it and noticing the dings and dats of the car, things I’m concerned on is the hesitating idle. It’s not rough or dragging it’s more of a split second ever so often when stopped of parked. Other is the loud vibration when I’m going on and off the gas slowly. It’s not dramatic vibrations it’s more of a giant electric toothbrush inside the car type of vibration. I am not sure if either are connected and what the causes are. Any answers or suggestions would help
