SOURCE: 1999 Nisian Maxima and need to know what codes mean?

P1320 Ignition Signal
Signal wire from distributor
P0325 Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)
O2 senor ( The one before the cat converter )
P0300 Random/Multiple Cylinder Misfire Detected
The misfire detection monitor, a software strategy built into the computer, is designed to detect an engine misfire. The computer can also normally identify the specific cylinder in which the misfire has occurred. A misfire is nothing more than a lack of combustion, which can be caused by poor fuel quality or metering, low compression, lack of spark or unmetered air entering the engine. There are other possible, less obvious causes as well, such as uncommanded Exhaust Gas Recirculatin (EGR), flow. When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc. In this case we have either multiple cylinders misfiring, or the computer simply can't determine the specific cylinder, and as such we are left with the P0300 in computer memory.
Possible Causes:
Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect fuel pressure

EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues

SOURCE: Vehicle start shaking and died. Has a trouble code P0300

Error code P0300 means that you are having multiple/random cylinder misfires.  I would start with changing all of the spark plugs and see if that will fix it.  You will have to have the code reset at an auto parts store.  If that doesn't work let me know and we can progress down the line.

SOURCE: check engine light on,running rough code P0172

When I see all these codes i instantly think of two things. Vacuum leak especially intake manifold gaskets and Mass air flow sensors. Spray the engine with carb cleaner when its running and see if you get it to rev up,run rough or run different. Next unplug the MAF and drive the car, see if it runs normal.

Losiento, mi espanol es no perfecto. S? c?mo hablarlo algo correctamente, pero yo no lo puedo deletrear repara, as? que tuve ayuda del Internet, espere que esto haga desde entonces.

P0300- esto es un fallo de tiro aleatorio, la necesidad de reemplazar sus buj?as y verificar sus rollos
P0113- esto es probablemente un malo 02 sensor, verifica el sensor r?o arriba en el compartimiento de motor
P0125-El motor no consigue suficiente caliente, su termostato probablemente es atascado abierto, esto debe ser reemplazado.
P0123- Algo est? equivocado con el sensor de posici?n de v?lvula de admisi?n, verifica los alambres esto tambi?n podr?a ser una computadora da?ada.
P0335- esto es el sensor de posici?n de manivela, otra vez, verifica el alambrado
P0351-esto tiene que ver con tiempo de ignici?n, consigue este averigu? por un profesional
P0358-El rollo malo posible en el cyclinder #1. Verifique el rollo conmutaci?nlo con un cilindro diferente, vea si consigue el mismo problema con el otro cilindro. Podr?a ser relacionado a la buj?a mala tambi?n.
P1258-La temperatura relacion? otra vez, debe irse con el reemplazo del termostato

Todo en total, no parece demasiado grave. Yo tambi?n limpiar?a el cuerpo de v?lvula de admisi?n con limpiador de cuerpo de v?lvula de admisi?n, con la bater?a desconectada. Debe ser brillante, cuando terminado, el viaje alrededor de durante 20 minutos con todos los accesorios de reponga la computadora. Tambi?n, trate buj?as de aire acondicionado Delco que utiliza modelan #41-103, estos motores adoran ?stos.

Need to what Cod #P1258 & P013 & P0174 &P0300 &P0404 Thank You


The 174 refers to your oxygen sensor's bank 2 (driver's side) system running too lean check wiring to sensor and pull sensor to try cleaning and retesting before replacing, 13 is an open circuit on your camshaft position actuator, check connection going to cam pos. sensor 300 is random or intermittent misfiring of cylinders can be related to faulty spark plugs, ignition coils or even a stopped up catalytic converter or exhaust system 404 is an exhaust gas recirculation valve 1258 refers to the ecu (computer) controlling the air/fuel ratio metering this is probably the computer trying to compensate for the other problems the 174 code is probably related too.
