That Sucks! Just throwing out some idea here. Maybe check all the related wire to the CPS and make sure that none of them are rubbing against anything cause them to arch. Make sure that the wires are in good shape Also make sure that the wires from the cps are not to close to the manifold causing them to over heat. Like I said just throwing out some ideas.
