If there is knocking at idle, it will be either Piston slap because the cylinder has worn at the top or bottom or like bernard,

Pre-igniton.

If it's Pre-ignition, your acceleration will be terrible, but you must fix this problem before it's to late.

That goes for the Piston slap, if you wait to long you won't be able to rebore the cylinder to the next size.
