I have an 03 century i changed the plugs and wires, and now it is running worse than before. Any ideas on what it could be?

Make sure you have the spark plug wires going to the correct ignition coil towers. It's very easy to mess up.

I have actually.did the plugs and wires yesterday and it runs significantly better but hardly stayed running at an idle.

Ringo, have you checked your fuel pressure and operation of the fuel pressure regulator?
No sir I have not.i don't know how at this point, tonight my lights quit working, thinking my multi function switch went out as well, so I will be dealing with that next.its becoming more and more expensive
