Knocking sound coming during acceleration but only in hot.
1. Cold engine is running fine and
2. With Hi octane running fine even in hot condition.

Without understanding the type and source of the noise, it is not possible to provide any comments.

Is it consistent with engine speed?
Does it occur at a constant rate?
Does it change with abrupt or constant throttle opening?

I have the same problem. It is consistent with the engine speed as well as if I accelerate it in nuetral. Moreover, I have also get it fueled with hi octane, the knocking becomes less but its still there.

Kindly guide me what to do.
