Problem 1: When i try and start the car, it turns over for like 10 seconds before it sputters to start, or i can crank it for a second, turn key back and then start it right up???????????

Problem 2: When i come to a slow stop, there is a pedal kickback and the car coast for like a second????????????

If anyone knows the solutions, are they do it yourself projects or something better left to the dealer?

Thanks
