Changed plugs and wires now car will not run right. Could the suggested firing order be wrong? If not what could be the problem?

Good morning,

Yes, check the firing order.

I attached a picture for you to test the firing order.

Make sure the wires to to the correct cylinder with the numbers on the picture.
