Default 98 Deville #1 misfire issue

Hey all. Ive about had it with this car and its issue after issue. So i drove to work Moday morning without any problems.
I go to drive home and it is misfiring. I get home and check the code and it reads P0301 Misfire cylinder 1. I have to leave for school in 15 minutes so I cant do much at the moment. I leave for school and the engine light starts flashing so i immediately turn around and head home.
I pull the #1 plug and its covered in gas it seems. I clean it and swap it with #2 plug. I also used my inline spark tester and there is spark going to the plug. The swap didnt do anything for the misfire.

Any ideas? Injector? Worse?
Its my daily driver to work and school, so its severely hurting me at the moment.

If you are getting fire than it is probably a bad injector.
