I need some help........

My 94 honda accord is making some kind of rattling noise, when the car is motion. When i accelerate at a certain speed(for ex. 35 mph) it makes a rattling noise underneath the car around the heat shield, and when i accelerate a little bit faster, it goes away and when i bring back to the same speed the noise begins again.................. Several people have told me that it might be the heat shield,it might of have bent,because my car was low before, when i had some 17'' wheels. My car would sometimes scrap from the bottom, so i don't know if it is that. Maybe yall have heard something like that and can maybe help me out. Please.........Thanks.

Sounds like a heat shield. Hondas got lots of them. At the shop I'd just tap on all of them with a screwdriver handle until I found the noisy one. If the welds were really bad, I'd just tear them off. If it was still hanging on, I'd use hose clamps to tighten it down. If it's too big around for one clamp, you can open them up and "chain" several together.

Pretty common that they will buzz or rattle at one specific RPM or load condition. Sounds like classic heat shield to me.
