Answer
Gary,
I'm not sure what type of ignition system the Sebrings use.  If it's a distributor type, you may have luck replacing the cap and rotor.  If it's a coil system, you may have a problem in the coil pack itself.  Have the compression checked in the #1 cylinder.  If there was a severe enough shock to crack that spark plug in the first place, there may be a bigger problem.
Good luck!
