Does the car even run at all?
When was the last time the timing belt was replaced?
Those codes indicate that the confirmation signal that the coil has fired is not present. Judging from other codes you have, like P1346 and P1351, which could indicate that your engine is out of timing, my guess would be that your timing belt may have slipped a tooth or two, so this is what I would start with.
Next thing to check would be your Spark Plugs, see how old they are and if either excessive buildup or any other mechanical damage is present. If that's good, check the wiring coming to the coils. First, start with checking that you have 12V and Ground on all the coils. Below is the pinout of the connector for the coil and ECU, Pin 1 of the Coil should be powered when the Ignition is in the ON position, Pin 4 is Ground. If there is no power, check 30A AM2 and 15A IGN Fuse, as well as the Ignition Lock. Other than that, check the IGF confirmation signal wire that goes to the ECU. From the diagram, all IGF signals from each coil come into one wire, which is then connected to Pin 23 of the ECU. Pin 2 of the Coil is responsible for the IGF signal, check that the wires for each coil are intact and have continuity with ECU.
Actually, the car runs great. But, last time I drove.it went into limp mode. Then I checked the codes. Timing belt.is supposed to be pretty new. Plugs are supposed to be new. But, the previous owner could have lied...I have no idea.

A lot of times if people don't unscrew the spark plugs before trying to align the engine, the timing ends up being off. Other than that, some negligent mechanics are too bothered to actually take the intake off and replace back plugs, but still charge the full price.
Again, I would start with checking the alignment first, since there are codes indicating something in there is out, and the ignition will not function properly if the timing is out.
