Trouble code P0301 is most likely due to a faulty ignition coil. To verify before purchasing one, try swapping say cylinder #1 and #2 coils. Clear the faults then start the vehicle. If the fault changes to P0302, then the ignition coil is definitely faulty. Odds are if one coil is faulty, the others will not be far behind to fail.
To make life easier, change all 4 coils and plugs at the same time rather than dealing with a faulty coil every few months until they all fail. Correcting this issue may also clear the P0411 code. If it does not, then the hoses for the secondary air injection system should be checked for leaks, breaks, etc.
