PEUGEOT GAS EATING

Friends, I have a 2001 model 1.4 Peugeot 206, the vehicle is not used for a long period of time, even if it waits for a night, it can be even 5 6 hours. Do you think there is no problem?

have the coils and spark plugs checked. These parts are problematic because they are made with gasoline, although they are not met frequently, they can also be caused by flywheel speed sensor.

2 days ago, I bought a 206xs 2000 model. When I stand normal in the car, there is no tremor in the car, and it is extreme. It continues until the exhaust of the car. I wonder if anyone have this problem
