When I start the car it is rough?

Hello,

It sounds like the engine is misfiring which means it will need a tune up, can I ask if the check engine light is on? If so, we should run the codes as well. These three guides will help us to get started on fixing the problem:

Inspect the ignition coil-on-plug assemblies for cracks, rips, or tears. Replace any damaged coil-on-plug assemblies. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
