Weird engine problem

Hi guys

This problem sometimes happened when my engine idled but it has become worst to a point that it's happening almost all the time. I'll try to describe the problem as best as I can.

When I turn on the car cold, it runs fairly good until I give it gas and it loses power and the engine starts to sounds like it's not running on all 6 cylinders. After a while that the car runs the power gets so low that if a heel is steep I have to give it full throttle in order to get any acceleration. The coils and spark plugs were changed about 7 months a go and I tested them by unplugging each coil while the car was running and the engine sound changed as I unplugged and plugged them back in. Fuel injectors were also changed yesterday.

Sometimes when I'm driving at fairly constant speeds in the highway engine returns to normal but after giving it full throttle the problem returns and the engine loses power and feels as if it's not running on all 6 cylinders.

I have run out of ideas. I also made a video that you can hear the engine while the car was in my garage.




If you guys would know what it could be please let me know.
