Could you give me any advise for this problem since the date I got this car. ?
Normally the car runs great if I drive it more often. However, if I leave my car idle for a week or so, I start getting a really big problem as

1. when I first start the engine and drive the car around for 30 minutes the car running is ok, but as soon as I stop the car and turn off the engine. The car can not be started and I usually have to wait for at least half an hour later in order to restart the engine.
2. During restart the engine, I can smell a bad smell comming the back of the muffler.
3. Sometimes, the car is suddenly stopped while driving and I have to wait for another hour or so in order to start the engine.

Please help!!!!
