Question

I hear a pinging sound when engine is hot and around 1400 rpm during the car accelerate after stop. There is also humming sound(best i could describe) when the car is at brake and park position.

Answer 1

You may have 2 unrelated problems. For the P0011 you could start by changing the engine oil, if the problem persist you may have to replace the Intake Valve Timing Control Solenoid Valve. The P0507 code means that the engine idle is not set correctly. For that problem you could start by cleaning the throttle body and set the engine idle. If the problem persist you may have to replace the Intake Air Control (IAC) valve .
