Hi Ibrahim,

Thank you for the donation.

It is never easy to noise problems and from your understanding of the noise, do you think it is engine mechanical or external knocking noise cause by something loose and hitting against a vibrating part?

A loose or out of alignment exhaust line, broken mounts etc ould cause knocking noises. The Idle control system is malfunctioning and this would reduce the idling rpm which would cause the engine to vibrate more and that could be the cause it

It could be a bad engine mount causing the shock when shifting into reverse.

P0505 would affect the idling speed and it most probably is cause by a stuck IAC valve located under the throttle body. Cleaning the IAC with carb cleaner might solve the problem.

As to the other 2 other codes, I am unable to find any data about them. Can you please reconfirm if the codes are correct?
