Mi Carro Corre bien menos en D

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

I need kit of seals and gasket for power steering KIA SPORTAGE 2000 or What can I do ?

SOURCE: cuando el coche esta frio,

no dijo que motor tiene el carro, pueden ser varias cosas, necesita revisar:
El regulador de presion de gasolina, cuando lo prenda quite la manguerita de vacio y vea si sale un poco de gasolina, tambien puede tomar una manguerita conectela al regulador y suervale fuerte si le queda sabor a gasolina el regulador esta defectoso, remplacelo le ayudara ahorrar gasolina y trabajara mejor.
El sensor de la temperatura para la computadora le esta diciendo que el carro esta caliente y no le pone la suficiente gasolina por eso se apaga, no es muy caro remplacelo.
Algo que no me dice es si el carro trabaja bien despues de calentarse.
Revise esto, escriba para atras si necesita mas ayuda o tiene mas informacion.
Buena suerte

Revisa el marco de las puertas, debes tener un PIN que se presiona cuando estas se cierran, que esta fallando. Es raro que todos a la vez, revisa puerta por puerta. A veces se soluciona echandole unas gotitas de aceite WD40.

Suerte.

lo que tienes que cambiar es las bujias y los cables otra ves y asegurarte que esten bien apretadas las bujias y los cables oh otra cosa puede ser que tenga una fuga de gas en los cilindro pero asegurate que las bujias sean compatibles para esa marca
