Change it without a doubt that keeps everything in one piece.

had this a couple of times on my blob when the wife accidentally put 95 ron in it (luckily not a full tank). Went away after a couple of days when I brimmed it with vpower.

I've also seen the knock sensor flag when there was a bolt rattling on top of the block, so check that nothing is loose or tapping.
