Engine shaking after replacing the spark plugs

Good morning,

I would remove them again and make sure the gaps are correct. Sometimes you get spark plugs and the gap is not there. It is non adjustable but there needs to be some clearance.

Another possibility is the boots on the end of the coils. Inspect them and look for any white marks on the boots. If you see that, the boots are leaking electricity and need to be replaced. You can just get the boots without buying the entire coil.
