Injectors provide your truck with the fuel needed to create more power. A bad injector can cause hard starts, poor fuel mileage, dead missing in the engine, and overall bad performance. Most injectors will last for 150,000 to 300,000 miles but that is dependent of several factors including fuel quality, fuel filtering, oil changes, oil quality, and so on.
