Customer Question

I just collect my car from the garage and my mechanic says that there is misfiring on the 6th cylinder, he swap the cylinders, he install new plugs but problem is still there. He connect car to computer which shows an error combustion misfiring. Do you know what can cause the problem? It is only happening when the engine is cold.
