10-5-7 · 4.0L - BUZZ NOISE - UPPER ENGINE

I have an 08 mustang v6 and I have a buzzing noise in the upper engine. It only really occurs around 1500-2000 rpms... So I was wondering if anyone had any info on this tsb, or the pdf of the tsb I could look at. Anyone else here had a problem similar to this? I do not know if this is the problem or not but I hope it is a simple fix. I used to think it was an exhaust problem, but after it got a little worse I found that it was somewhere around the top of the engine.

Ok I took my car to ford today and they told me that the coil pack bracket was the problem. and they fixed it ... supposedly.I was fine for a while, but it is rattling again now =/. If I have it in gear and hold the brake and rev till it rattles my dad can just push on the bracket a little and the rattle stops.. lets go and it starts again. So my question is if they tightened it down why would it loosen up so quick? Is there any other fix for this?

I would imagine it loosened up like that cause of the vibration from the motor! Never heard anyone with this issue but did they loctite the screws? Or I would look to find something to make it more rigid!
