I have been having a rattle that sounds like its comming from the right side of the car, some where underneath the middle. This only comes when I accelerate. I can play with the gas and hear it when I push down, and then stops when I let up. Any ideas what this could be? It seems to be more noticable at lowet speeds and RPMs. I searched and the only thing I could find is the heat shield? Could it be muffler, etc.?

 

id say maybe a heatsheild? Is id deffinatly outside teh car and not something in it?

 

Yea its forsure outside the car, sounds comes from the passanger side.

 

I got the same problem, its resonates esp. at 1.8k rpm. Sounds like rattling in the door or pillar.

Haven't had time to really look into it. Let me know if you figure it out.

 

Maybe the cat heat shield.

 

I HAVE SAME PROBLEM MINES COMES FROM DRIVE SIDE IT BEEN GETTING ON MY NERVE I PICK UP THE MUSIC SO, I DONT HAVE TO HEAR THE RATTLE. THE GREASE MONKEYS FROM ACURA DO NOT KNOW HOW TO FIX THE PROBLEM WHEN I WHEN TO SERVICE THE CAR. I DONT KNOW WHAT TO DO

 

I was on a long trip with my girlfriend and she tracked down the noise to my sunglasses in the sunglass holder.

So take it out and see if it still rattles.

I hope that helps.

i got the same problem the heatshield is tight. maybe a the cat? if the cat is cracked wouldnt it throw off the check engine?

 

Not necessarily. Small pieces can break loose inside and the cat will still function properly. Check the heat shields first. It's an easy fix.

 

i had a problem like this on my old 96 accord..... it was a cover somewhere on my exhaust, my mechanic put it on a lift ripped it off and say bye.

 

Yeah the heat shields are not a necessity. Just don't park your car over top of dead leaves.

 

i think they are dual purpose though...the heatshields or 'cover' as in the parts manual. they are there so rocks won't fly up and puncture the cat i believe too, not just for a heat barrier. but if you want to risk a 600 or 1000 dollar part if you are a type S driver, take that cover off then.

 

Id like to see that thin little sheild stop a rock. If its strong enough to puncture the cat, it will blow right thru the shield with out even batting a eye.

 

well if kris, the god of acurazine says so, then it must be true.

 

I had this same problem, it was the heat shield for me located over the front right cam shaft. They replaced the shield under warranty and I haven't had a problem since.
