Could it be one of the coils where you spark plug goes in?

Question

The code that is showing is P0307. I was told it was the coil.

Hi there

Yes, a bad coil will cause a misfire code. On this it could be the #7 coil causing the issue. Its a good idea to check the spark pug as well because it can cause the coil to fail if it's old and worn out. The boot off the coil to the plug can cause the issue as well.
