I'm having an issue with my 2016 ford fusion 2.5. 63k mil. When coming to a stop in drive, there is a noticable ratling noise from the engine bay accompanied by an occasional idle surge. The rpm will slightly drop, and when it does the whole car will pulsate and will shake for a second (i can feel it in the seat). Running the car with the ac on will make the noise and idle worse. Ac is fine and blows cold air. I've gotten the top (main) motor mount replaced ~1000 miles ago, which is what the dealer determined. Drives much better, But the issue persists. Other than that, the transmission has gotten a bit wonky lately and shifting feels harder than usual. No check engine light. I'm suspecting the chain tensioner/ac pulley bearing may be bad but I am not sure on what could be the problem. Would greatly appreciate any advise on this.

Curious if anyone can tell me which pulley this is. It obviously has a large crack in it and needs to be replaced, but I don't know which one it is to go buy a new one. (I'm almost positive it's not the belt tensioner, and all the pictures of idler pulleys I've seen don't have grooves in it like this one does.) This is a 2012 Fusion, 2.5L, automatic. For reference, it is the closest pulley to the front of the car. If you were looking at the side of the motor that has the belt, it would be on the top right. Thanks for any help.

New to the forum, hopefully this is the correct area to be posting this. Hoping someone could give me a little help on this. I have a 2008 Fusion that has a rattle from hell when the engine is at an idle and under some sort of load, power steering, A/C, the alternator, whatever. Sound like marbles in a can. It is especially bad when the car is in gear. You can watch the serpentine belt tensioner jump around as it makes this noise, and if you apply some sort of pressure to the tensioner while it it running it stops. With the belt off everything seems to spin freely. I've already replaced the tensioner (with a Motorcraft one), belt, idler pulleys and the alternator when it gave out. It's been going on for a while now and I can't seem to figure out what is causing it, and I can't really afford to throw parts at it since I'm going to school at the moment. Is there some way to diagnose what is causing this? Or has anyone else had a similar problem? I've hit a bit of a brick wall here, as I do not know how to check what could be causing this.
