Engine knock when initially giving gas
I have a 2013 CanAm Maverick with only 80 hours on it. While idling there is no engine knock. However, while in park or in gear, when I first depress the gas there is a succession of 4 or 5 engine knocks, or 4 or 5 engine rattle sounds. If I continue to give it gas they stop. If I let up of the gas, and then depress the gas pedal again it will again do 4 or 5 knocks.
What is this?
