I have a weird rattle noise mostly happens when decelerating, and sometimes when accelerating, not an engine type of noise, anyone have this problem before, thanks for any tips

 

Where is the noise coming from and how does it sound? It can be an exhaust leak, or something entirely different.

It's hard to give an accurate answer without any details. Even so, it's still hard to analyze over a forum.

 

I gues that would help, well sounds like it's coming from under the left side of the engine, it's odd sounding. sounds like a heat sheild but when I checked the sheilds they don't feel loose or anything,
