My 04 F250 has 122K miles on it and is still runnin strong with the usual maintanence, oil, filters, emmisions system, etc. Should I be looking at replacing the fuel injectors some time soon? Does anyone know the service life on these, has anyone had injector (2 or more) falure at 130K, 150K? I am planning on keeping this truck for a while.
Don't worry about it until you have one fail. There's really no telling how long they'll last or which one will go so you just have to wait. Also, there's no guarantee new (rebuilt) injectors will last any longer than whats in there. Best to leave things alone if its running well.
