So lately my truck has been having a more buzzing type of vibration on top of the bad motor mount vibration, and when I shift to reverse and push the pedal the rpms drop to 450-500 then come back up before it moves, also when driving at night my lights inside and out dim when I let off the pedal for a second then return to normal brightness, not really a major problem I just am not sure what the cause is
