12 is battery disconnect within the last 50 key-on cycles, don't worry about that one. The 43 is a cylinder misfire, 99% of the time it's one or more spark plugs that need to be changed. Go get you some stock Champion sprak plugs from Autozone, O'reilly's, NAPA or whatever store you prefer and change the plugs. After that pull the fuel pump fuse out from the PDC for about 10 minutes, then reinstall the fuse. This will reset the computer. After that if you still get the code 43, then you need to inspect your spark plug wires and coil pack for any cracks or defects. In fact, check them when you are changing the plugs.
Again, buy the stock Champions, don't buy platinum plugs!
