Rough idle

Hi,

You have what is called coil on plug ignition coils so there are 6 of them. Due to this being the case, you can test each coil but it is better if we use a scan tool to find out it there are any misfires.

Rough idle can be caused by many things so if there is no check engine light, let's check for vacuum leaks first.

I attached the various tests for the coil if you locate a signal or multiple misfires.
