The variable valve timing system uses oil pressure and solenoid control. If the system is not working properly or the oil supply is restricted to this system a knocking noise can occur which can get louder on acceleration and if the timing is not being correctly adjusted the engine could stall. A Check Engine Light may be accompanied with this so faults should be read out as well especially if the engine stalls. You may want to enlist the help of a mechanic, such as one from YourMechanic, who will be able to determine the type of noise, locate its source, and repair the issue to correct the noise and stalling issue.
