name three things that might be causing a ringing chain dragging noise underneath my 04 gt only when the car is moving. usualy between 2500 and 3000 rpms. not a constant noise but everytime i drive it will happen..

 

[fasterthanthem]

Loose bolts/nut along the exhaust somewhere?
Or possibly the exhaust rubbing on the chassis/body?

 

[Stark77]

loose O2 sensor

Check the exhaust heat shields, they can make some funky noises when they are loose or bent/rubbing.

Does it happen more over rough roads or is it more based on engine or vehicle speed?

you sure its not a lose spark plug?

 

[mransr]

+1 on the spark plug

or maybe a cat coming apart (if you have cats)

 

[Mustang5L5]

brake splash shields?

 

[R.J.]

Metal EVAP line fell out of its clip above the drive shaft? (happened to me)

 

[98coop]

cat shield, header bolt, o2 sensor loose

where are the heat shields on the exhaust? its really not on speed it happens mainly between 2500 and 3k. but it could happen at other rpms. rough roads dont make a difference

its coming from under the car. i dont think it could be the spark plugs

He might not have the heat shields with the aftermarket H or X pipe he has. When I put on my Bassani X pipe I never put the heat shields back on.

brake splash shields?

thats the metal peice infront of the brakes? idk i tried messing with those, i dont think its that. good idea though

 

[oxfordgt]

Are the joints in the exhaust hitting the floor board?

You sure the car isn't pinging? It can make that noise you discribe. You say that it usually happens between 2500-3000, but what kinda throttle are you giving it?
