well, it means exactly what you have here. P0141 and p0155 are usually bad o2 sensors, on occasion it can just be a wiring issue. Lean bank 2, hmm could be a vacuum leak, could be dues to the o2 sensor. p0300, random missfire, your fuel injector assemble is the first suspect but could also be a vacuum leak or bad plugs. p0719 is the input to your torque converter clutch, either wiring, brake light switch or the TCC lockup solenoid

p0174 fuel trim system lean bank 2 p0300 engine misfire detected. P0300 has been set due to the first code. P0174---The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. There could be a vacuum leak downstream of the MAF sensor.
