I have a 1991 suburban with a 6.2liter "J" engine stock that has begun to start hard. All the glow plugs are new and the glow plug controller is new. I have 186000 on the original pump and injectors that i assume ( from what i am reading) that should be replaced based on what I am experiencing.
Because I want to do upgrading as I can afford it my plan was to replace the injectors with 6.5 liter high flow injectors (bosch) and aremanufactured injector pump and adress exhaust and air as I go. Is there any trouble at this point of going with this type of injector or am I missing the boat and should i stay with standard injectors?
