2004 Nissan Quest engine knocking noice, please help!!

[Weijie0192]

My 2004 Nissan Quest has this engine knocking noice (sound like popcorn). When I start the car, it will die off immediate unless I press and hold acceleration.

Using my scanner I receive P0300 code - random misfire. However, I have changed all the spark plugs, coils, camshaft position sensors, and solenoid, but the issue persist.

The car currently is in a undrivable state. Does anyone encounter the same issue and has a solution for it? Much appreciate for all the help!

Here is a video of the sound
