Hey, I have a 02 Grand Prix GT with about 115K. Ive had this car since 65K. When I start the car, the car kinda shakes for a few seconds (like if someone pushed it) when I turn the key. The car always starts and I still get good mpg. It still has a smooth quiet idle. Its just that the car doesnt start as smooth as it did when I first bought the car. Ive never had a tune-up. So do u think its the engine mounts or a tune-up even though the car runs smoothly.
