Car Stalls at low speed. Restarts. DTC Code 0340 and 1167

Trouble code P1274 in a Nissan Maxima is defined as Air/fuel sensor reading a rich fuel mixture. It also points to the upstream AF sensor on Bank 1 (the side of the engine near the firewall). The AF sensor is also referred to as the oxygen sensor located on the exhaust manifold before the catalytic converter. Depending on how many miles the car has, this sensor might need replacing. Technicians do recommend replacing both upstream sensors as the AF sensor on Bank 2 (the side of the engine near the radiator) might go bad as well. Other causes of trouble code P1274 are faulty injectors, improper fuel pressure, or a malfunctioning Mass Airflow Sensor.
If you wish to clear the codes temporarily, simply disconnect the negative battery cable. Wait a couple of minutes, then reconnect. If no repair was performed, the trouble code light might return after a few miles of driving. State Inspection requires that all monitors are ready during emissions testing, so make sure that you have completed a drive cycle (about 3 days or 50 miles of driving) before submitting the vehicle for an emissions test.

430 is Oxygen sensor

0305 is misfire on cylinder 5

1320 is ignition coil.

The ignition coil is causing the misfire. That is causing rich mixture which could case the oxygen sensor issue. You need to work from the ignition issue to the sensor. The reason is if you replace the cat and the engine is running rich it will heat the cat up to the point that the car might catch fire. Oxygen sensors are also prone to fail after about 60 thousand miles.

Obviously its problem with your fuel to air mixture. It is building up unburnt fuel due to not enough oxygen. This lack of enough oxygen will cause the stalls and the build up of gas will cause the backfires. Heat affects the mixture ratio. A number of detector are involved in the exhaust system and any one of them could be failing. Throttle Position Sensors, MAP sensor, Oxygen sensors, catalytic converter, etc. You should be getting the check engine light coming on also. Any auto parts place can read you the code numbers for free. They will provide more specific information about failing parts.

Well, sometimes you get lucky replacing parts, but usually its something other than the component in question.
The trouble codes are a guide as to what to test, not what to replace.
Code 325 is for the knock sensor which could be a phantom code.
Code 100 is for a bad signal from the MAF sensor which may or may not be caused by a bad sensor. It could be a vac leak too.
Code 110 is for a bad signal from the intake air temp sensor. The signal tells the computer what the temp of incoming air is to help the computer decide how rich the fuel mixture should be.
You need to get the testing procedures for each code and follow them. I would skip code 325 and start with code 110.
The fuel pump was probably a waste of money unless you checked fuel pressure before you replaced it and it was low. Same thing with the O2 sensors. Very rare if both sensors fail at the same time.

A code P0300 may mean that one or more of the following has happened:

• Faulty spark plugs or wires
• Faulty coil (pack)
• Faulty oxygen sensor(s)
• Faulty fuel injector(s)
• Burned exhaust valve
• Faulty catalytic converter(s)
• Stuck/blocked EGR valve / passages
• Faulty camshaft position sensor
• Defective compute
• P1105MAP/BARO Pressure Switch Solenoid Valve
• Check and clean the MAP sensor, or replace.
• P1492EVAP Canister Purge Control/Solenoid Valve (Circuit)
• Replacing the purge solenoid will clear code P1492 This should also clear code P0300 as well.
  

It shoudn't be. Your oxygen sensors detect the oxygen in the engine. A misfire can be a few things, such as spark plugs/coils, wires, distributor cap and rotor, cam sensor, crank sensor, ecm. I would start with a tune up. If it has been more then 75,000 miles since you changed the plugs and wires, it could be that. Has it been acting up, such as hesitations, stalling when you slow down or stop?

oxygen sensor

could be the oxygen sensor manybe, or fuel pump

code p 0138 refers to 2 items
1--heated oxygen sensor(HO2S) 2 bank 1--high voltage ==causes --wiring short to positive --HO2S---ECM
2--oxygen sensor (O2S) 2 bank 1--high voltage ===causes wiring short to positive ---ECM
code p 0139 refers to 2 items
1--- heated oxygen sensor (HO2S) 2 bank 1--slow response ===causes --heating inoperative --wiring--ECM
2--oxygen sensor (o2S) 2 bank 1 slow response ===causes --wiring --- O2S

heated oxygen sensors9HO2S) are in the exhaust manifold before the cat converter
Oxygen sensors (O2S) are after the cat converter
it is indicated that the HO2S is faulty-
check the wiring and /or replace both sensors

I had a similar problem and resolved it by replacing the mass airflow sensor. Ive got 235k+ miles on my 1992 Maxima SE.
Still runs good but having problems with the alarm system.
