2.5 Knocking Noise—Only under load...? (VIDEO)

Hi all,

So over the course of the last few months there's been this super intermittent knock that comes about. Only under load, so far. Even then I can't reproduce it. Typically when going up hills. Increases in volume when I apply the pressure on the gas pedal. But whats tricky is that I can't find the right circumstances that reproduces the sound... I could really use some help on this. Ideas? Rods? Lifters? Loose pulley?


Thanks guys!

Nick

Try cleaning the mass air flow sensor and seafoam the engine.
