The truck has developed a significant knock coming from the intake manifold. It is loud enough to hear with the hood closed. The problem exists warm and cold. The knock was verified by Sunrise Ford in Fontana, CA in December of 2024. The Dealership had another F250 on the lot with the same 6.2 engine and that it also has a knock coming from the intake manifold, so they considered the situation "normal". There is a significant amount of information available that the knock is related to an impending failure of the Intake Manifold Runner Control (IMRC). If the IRMC fails, the parts will go into the combustion area and could cause an immediate catastrophic failure of the engine. At best this problem creates a loss of power and a pulsing vibration at idle.

(UNKNOWEN) I have a problem with accelerator pedal lag time, when pushing down on the accelerator pedal nothing happens at first then you get acceleration which isn't good it's like the truck falls on its face then jumps forward. This is a real problem when driving in traffic or really any time. I have spoken with Ford about this problem but all I get is that's the way it is, Ford needs to fix this problem it's a safety issues, I have looked on-line and I'm not the only one with this problem. This lag problem happens at any and all speeds.
