what could cause this ???????????

Can you do that from the motor side of the car?

When is the last time you did a tune up? Plugs and wires?

It's in gear in the video? Does it chug in park?

we were thinking same thing why I wanted an engine side video to double check the sound!

yeah its in gear. I have tried it in park but it wont do it.

Haro i had plugs and wires done on it back in the spring and thats when it started acting up. A few weeks ago i had the front motor mount replace and was getting a misfire from plugs 3/6 so i changed those and one of the mount on the backside of the motor was change and it ran fine for a few days then went back to chugging and bad idle once car is warmed up

Put it in gear apply parking brake and slightly pull on the throttle body accelerator, as your recording the video

How old is your fuel filter?

I changed the fuel filter back in the spring when i did the plugs and wires

I'd check your fuel pressure at the rail. Either tape the guage to the windshield so you can see it, or have someone else in the car put the car in drive and hold the brake while slightly pressing the gas pedal. IIRC, the pressure should be ~42 lbs of pressure. If you're seeing significant drops then you have a weak pump, clogged filter, or faulty pressure regulator.

The lack of CEL and the fact that it only does this under a load makes me think it's fuel related. That has been my experience in the past with similar situations.

This is the best i can do but here is a video of the motor and chugging outside of the car

Here is a video of the motor

Does it ever not chug? Always chugging? Does it get worse under certain conditions?

It chuggs under load or after warmed up when sitting in park drive or reverse when its cold it really hasnt done. But it never does it while sitting in traffic on when driving in traffic
