I have been trying to find this problem out for a while. Over the summer it was not so bad. I did not drive for two days and I started it today and knocked louder than usual. I have read that it's the gas but I don't know. It's only when I accelerate and for a few seconds or it warms up should I put it.
have the same problem?
