Does your car have a "Service Engin Soon" light on?
If yes then take it to have it scanned at a auto parts store that does that.

If you have no light on then check your ignition coils, could be any number of sensors but it should have a "Service Engin Soon" light on.

 

i scanne the car and there are.....missfire cylinder 1-2-3-and 4

 

Did you already Check ur coils???

 

2 coils broken same time....???? i will check all idea because i dont have idea

 

Do you remember the code(s) number it has?

 

code p0300 p0204 p0203 p0202 p0201

 

Sounds like a coil pack , if one is going then the car will drive like **** .

It could very easily be a coil pack and one bad will make the car drive like crap.
Could also be bad/mis gapped plugs or bad wires.
I'd start with this stuff and go from there, or just take it to a shop and have them trouble shoot.
