One of your codes I could not identify and that was PO243? Do you have a description for that code? PO410 for the air injection code I would recommend you check all your vacuum lines. The rubber grommets collapse and will either cause a restriction or a vacuum leak. Here is a diagram of the lines.
Pay close attention to the rubber hoses at component #3 towards the back near the exhust, and #4 and #5 towards the front near the fan and close to the intake. If the hoses look defective or if you touch them and feel all gummy, replace them and reset the light. As for the first code, it indicates a problem with the mass air flow sensor but I would recommend you replace any defective lines you find during your air injection inspection since a vacuum leak can trigger a false air mass meter fault. Let me know how it goes.
