ºsaludos a todos,yo estube un problema similar y nadie daba con la solucion.al parecer es un mal de estas camionetas.un especialista en ford me dijo que cambiara el aceite 5w 30 a 15w 40, ya he rodado mas de 20 mil kilometros y se le quito el problema,de todas forma es desicion de cada quien ya que unos dicen que se tapan los ducto y que daña las camaras,ojo es semi sintetico.ojala esta informacion ayude a otros
Buenas noches amigos, soy nuevo en el foro y no se como se crea un nuevo tema, pero necesito ayuda, tengo una ford explorer 4.6 2010, soy de venezuela, la camioneta presenta codigos de fallas que tienen que ver con mal funcionamienfo de algunos cilindros codigos (P0300, P0302, P0304), las posibles causas son problemas con las bobinas de encendido, problemas con las bujias, problemas con los inye tores, lo que causa que el motor tiemble cuando esta en minimo pero no es constante se normaliza por largo toempo y luego buelbe la falla, ya probé desconectando los inyectores uno por uno y al hacerlo el motor tiembla con cada uno loque me indica que los inyectores estan bien, y si la falla fuera constante pudiera pensar que son las bobinas de encendido o las bujias pero la falla no es constante como ya dije , quisiera que me ayuden por favor gracias.
Buenos dias Sres, tengo el mismo problema con mi ford explorer v8 4.6 año 2010, soy de venezuela, el inconveniente comenzo cuando cambie el aceite, siempre utilizaba 10W30 pero por problemas a nivel nacional de abastecimiento, ese aceite es difícil de encontrar, tuve que recurrir al 5W20 que según la tapa, es el remendado por FORD, todo bien hasta los primeros 1000 km, una mañana procedo a encenderla y sono como si fuese un diesel y a los segundos se le quita, desde alli la camioneta parece un poto el ruido al encederla es fuerte, leyendo sus comentarios unos comentan que es la cadena, otros foristas indican que cambiando el aceite a mas grueso, realmente que sera?? si me pueden ayudar se los agradeceria.

Buenos dias tengo una explorer año 2010 motor 4.6 3V. el motor fue reparado hace seis meses por un problema de lubricación que presento y desde el momento de la reparación el motor suena como un motor Diesel. un mecanico le desconecto las valvulas VVT y dejo de sonar, solo suena al momento de encenderlo en la mañana o en cualquier momento del día y al ponerlo en marcha deja de sonar.
lo que he notado es que en subidas tiene poca potencia debe ser por la desconexión de las valvulas VVT
el mecanico me ha sugerido bloquear las valvulas VVT para que el motor mejore su rendimiento.
quisiera saber su comentario respecto a la recomendación del mecanico de bloquear las valvula VVT.
y si por estar desconectadas las valvulas en este momento el motor pudiera sufrir un daño mayor.
