Knocking when accelerating

Hello, the definition of "knock" can vary, so it is difficult to assess what you are experiencing. An internal engine knock could be a sign of severe internal engine damage, so it's something to have assessed before continuing to drive or operate the vehicle. You could also have a knock from pre-ignition due to engine timing concerns or fuel / spark / air ratio and quality concerns.
