SOURCE: mi dodge neon sxt 2.0Laut 04.me da un codigo p0300

Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
Symptoms may include:

• the engine may be harder to start
• the engine may stumble / stumble, and/or hesitate
• other symptoms may also be present

,,
Causes 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 computer

Possible Solutions If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open

The Dodge P1494 engine light code means Leak Detection Pump Switch or Mechanical Fault.

A proper diagnosis must be done, you can't simply replace the LDP and expect that to fix the problem. It shouldn't hurt anything to keep driving it for a while until you can get it fixed.

There is a technical service bulletin that applies to your vehicle and it mentions that code specifically. I'm including it here for your information:

TSB-18-01-00
SUBJECT: Misdiagnosed Leak Detection Pump Systems With DTC P1494, P0442, P0455, OR P0456.
MODELS:
1997 - 2000 (LH) Concorde/Intrepid/LHS/300M/Vision and others!

DISCUSSION: During evaporative system diagnosis, Leak Detection Pumps have mistakenly been replaced. A thorough inspection for pinched, kinked, or disconnected supply vacuum lines (as currently listed in the Powertrain Diagnostic Procedures) is a critical step in diagnosing DTC P1494 (LDP SW OR MECHANICAL FAULT). Additionally, the other evaporative leak faults (DTC P0442 - SMALL LEAK, P0455 - LARGE LEAK, and P0456 - VERY SMALL LEAK) should have the supply vacuum lines examined for pinches or kinks prior to any LDP component replacement. The supply vacuum lines should be checked from the engine compartment all the way to the fuel tank, including the LDP and purge system.

NOTE: VERIFY ALL RELATED SUPPLY VACUUM LINE ROUTINGS FOR PINCHES, KINKS, OR DISCONNECTION'S BEFORE REPLACING LDP SYSTEM COMPONENTS.

El Dodge motor P1494 c?digo de luces de detecci?n de fugas de la bomba o el interruptor de falla mec?nica. Un diagn?stico correcto se debe hacer, no se puede simplemente sustituir el PLD y esperamos que para solucionar el problema. No debe doler nada que mantener la conducci?n por un tiempo hasta que te lo arreglen.

Hay un bolet?n de servicio t?cnico que se aplica a su veh?culo y se menciona que el c?digo en particular. Lo incluyo aqu? para su informaci?n:

TSB-18-01-00

ASUNTO:
Diagnosticado de fugas Sistemas de detecci?n de la bomba con DTC P1494, P0442, P0455, P0456 O.

MODELOS:
1997 - 2000 (LH) Concorde/Intrepid/LHS/300M/Vision y otros!

DISCUSI?N:
Durante el diagn?stico del sistema de evaporaci?n, de detecci?n de fugas bombas han sido sustituidas por error. Una inspecci?n minuciosa de las l?neas de vac?o pellizcar, torcer o desconectado de suministro (en la actualidad figuran en los Procedimientos de Tren Motriz de diagn?stico) es un paso cr?tico en el diagn?stico de DTC P1494 (PDL SW O AVER?A MEC?NICA). Adem?s, los otros fallos por evaporaci?n de fugas (DTC P0442 - peque?a fuga, P0455 - fuga grande, y P0456 - MUY PEQUE?OS DE FUGAS) deben tener las l?neas de alimentaci?n de vac?o examinados por pellizcos o vueltas antes de cualquier reemplazo de componentes del PLD. Las l?neas de alimentaci?n de vac?o se debe revisar el compartimiento del motor hasta llegar al tanque de combustible, incluyendo el PLD y el sistema de purga.

NOTA: VERIFICAR todo lo relacionado SUMINISTRO DE RUTAS l?nea de vac?o PIZCAS, torceduras, o desconexi?n ANTES DE CAMBIAR LOS COMPONENTES DEL SISTEMA PLD.
