Hello. Welcome to Just Answer. Please allow me to assist you. The P0302/304/306 codes indicate cylinders 2-4 and 6 misfires. Normally, we would suspect coil pack issues. However, with the P1351 code present, this is more than likely the issue. The P1351 code relates to the variable valve timing control system. Either you have a faulty Variable valve timing control valve, a bad sensor, or there is something wrong with the variable valve timing control gear on the end of the camshaft on the radiator side of the engine. Without the Toyota scan tool, the P1351 code is impossible to diagnose yourself. I would recommend a shop with a Toyota or highly compatible scan tool diagnose the variable valve timing system for you before doing anything else.

You did not address the air fuel sensor codep0125 for calif models. should I ignore that code
Toyota Mechanic: Toyota Service, Toyota Expert replied 5 months ago

The air fuel sensor code (P1133) is not the same as a P0125. A P0133 is a slow response oxygen sensor (faulty O2 sensor). A P0125 is cooling system not at operating temperature (faulty thermostat). I would not be too awful worried about the P1133 until the P1351 is sorted out. The P1133 may bne a RESULT of the other codes..
