I put new spark plugs and spark plugs, wires, and a new coil pack and now it's back firing... What could make it backfire?

Hi there. The first thing that comes to mind is crossed plug wires. I would double check to make sure the wires are connected in the right order. I have provided a diagram showing the correct firing order. Please let me know if you need any further help.

Thank you... And I followed your diagram and the back 3 wires were crossed so now the car is running good.
