First, what was the light on for prior? Next, for them all to misfire, that leads me to think of something such as a crankshaft position sensor. Did it ever do this prior to having the work done?
I attached a pic of the sensor I mentioned. This sensor is responsible for fuel injection timing, ignition timing and can cause several issues. Check to make sure the connector to it wasn't damaged.
Also, let me know if there were any other codes found.
