My heat shields were rattling pretty bad, tied em up and it solved my issue. I still get a rough idle sometimes, at about 600rpm my car goes rough. It sounds like the passenger cat shield might be loose, or the shields wrapping the exhaust? Give those a shot and see what happens. (I have a hole in my exhaust, so I can’t quite hear everything perfect in my car)
What did you use to tie up the heatshield? I get such annoying rattling at idle sometimes, other times nothing. Def coming from under the car. Plan to fix it next time I do an oil change.
I had that same rattling sound thinking that it can possibly be the heat shield but it ended up being the windshield washer reservoir with a broken plastic clip.
I checked mine and it was really loose, replaced with a bumper push fastener as shown in your pic and it's snug now (see pic with PN below). Over the years, I have replaced so many of these clips under the hood and fender wells, which keeps vibration related rattles to a minimum. We could almost start a thread on the topic. I also use MD weather seal on alot of potential rattles (where high temps are not a concern, like the fuse/power line for my sub amp - see below) and to reseal things like the air boxes:
Additional question, the black cover that hides the battery has clips on the ends to hold in in place, but the center portion is plastic sitting on top of metal. Would that be a source of vibration related rattles?
