P0300 is engine misfire detected.P0401 is for low or no egr flow.P1200 is an injector circuit failure.P0300 and P1200 are probably related.You need to check all of the injector wires and connectors for damage.P0401 may just be a clogged egr port between the valve and the throttle body area.You can clean it out with a stiff wire from both sides.The valve and throttle body will need removed to do it.They both are held on with two bolts and have wiring to disconnect.
