What's that noise....!!!!! I have been hearing this noise coming from my engine.....it started probably about 20,000 miles ago but it wasn't that bad and rarely happened... but now it is happening all the time. When i am in a high gear and have the RPMs below 2800 and give it gas, not even WOT but just get on it a little bit, a noise that resembles a coke tab rattling around inside of a can occurs. 
This crap is getting annoying....I haven't changed my spark plugs yet and the car has 76,000 miles on it....I know I know.....so i dont know if maybe the engine isn't firing on all 8 all the time due to the plugs fouling out or what???? I'm hoping this isn't anything major.....if anyone has had this noise or has an idea of what it can be please let me know!!!

sounds like pinging. try running some sea foam, and changing the plugs. It's what I did, and it did the trick. Also go get your tune checked by someone with a scanner and tuning software

dude, unless you want to spen some extra cash on a new motor, like me!!!..... you gotta be up to date with your maintanence. Im not picking on ya, its just you kinda sound like me a bit (i know, i know.....) and that turned into a deadly thing, which did get me a 408 but...........thats not the point. Just be careful and take care of her.
Now, the noise, is it a stable sound meaning, it is consistent with rpm's or random like if you are shaking the coke can a different speeds and intervals. Ok, those it sound like somethin is loose in there or tapping continously inside the motor?
That would help out figuring the problem. Change the plugs, wires, clean the filter, run the seafoam stuff, and see what happens. The worst thing is that you could take the covers off and see what you find.
How about bad gas? WHat kind of octane you putting in that motor?
..............and off course, there could be something in the bottom end that doesnt like the current situation, which isnt good.
good luck!!

My roomate's 02 SS has the same noise happening in 6th gear when you give a hard accel. It's pinging, but at least it only happens there. You shouldnt be accelerating hard in 6th anyway, it's really intended just to cruise.
