What you are hearing is probably a heat shield on the exhaust system that is loose. It won't cause any harm to drive it like this, it's just annoying. A 'cheap fix' would be to jack the car up, support w/ safety stands, look for something loose on the exhaust system (make sure the car has cooled off, you don't want to grab a hot exhaust pipe), You can usually re-attach the loose shield with something like a wire coat hanger. It may require drilling a hole in the corner of the shield, and then securing the wire after running thru the drilled hole. If you choose to take it to a garage, have them show u what's making the noise, and suggest this fix. If they want to change major exhaust components, tell them u would like to do this, and not an expensive repair at this time. good luck countrycurt0
Another possibility is the engine 'pinging'. I'm assuming the noise is coming from under the car, engine pinging would come from the engine itself. If you believe the noise is from the exhaust, ok, if not let me know. cc

SOURCE: It's making a rattling noise

Your rattle is coming from teh catalytic converter on your vehicle. Depending on the mileage, quality of fuel used, etc the catalytic converter can be damaged. It is best to have it replaced and at the same time have the intake system cleaned to prolong life of the new one. Average cost is 200-400 dollars for replacement.

Rattling noise when I press the gas pedal or when the vehicle is running idle.


Hi,
Likely an exhaust heat shield. When the SUV is cold - after sitting for 4+ hours - crawl under the vehicle and see if any of the shields are loose that cover the exhaust pipes. If they are you can use sheet metal screws screwed into the shield and against the exhaust pipeto 'wedge' the shield so it doesn't move.

When i press the gas pedal i can hear a rattling sound


Hi, there a couple of things that can cause this rattling type noise on acceleration the most common was the serpentine drive belt tensioner there was a service bulletin to address this. That bulletin number is EG021-07. The other problem is with the heat shields on the exhaust have a tendency to rattle also. I would have your local mechanic inspect both of these issues have them pull the service bulletin to verify whether not yours has been replaced or is making noise.

have you had the catalytic converter checked. When they break apart they will make a rattle ling noise. eventually the broken pieces will plug the exhaust and cause a lack of power feeling. When the exhaust is cold hit the bottom of the catalytic converter with your hand. If it rattles it is bad and needs to be replaced.

1999 Honda CR-V rattles during acceleration


Usually it is a loose rusted exhaust heat shield or shields.
Slide under and tap the exhaust system and shields from front (on the engine )to back.......there will be at least one rattle heard.

Check the heat shield to the exhaust manifolds, good chance that the bolts on them have rusted off or is loose causing the Heat Shields to rattle making the tinny rattle noise. Good luck and keep me posted, be glad to know if that's making the noise, and if not we can look at other things.
