1996 Chrysler LHS running rough...?

I have a 1996 Chrysler LHS that is running rough. I changed the spark plugs; still running rough. One of the plugs was covered with oil when I took it out. Doesn't sound good. What are my options? Thanks

Update:

Check engine light is on. Local Auto Z*** hooked it up to the scanner. They said plugs and O2 Sensor.
