bump...argh...
I did a search on this...not too many results...
And I really don't have the patience to go see the dealer, AND to explain to them, because it only really seems to happen under hard acceleration. I also haven't been worried too much about it, because again, it only happens sometimes, and it doesn't sound like anything 'significant' because there's no loss in power (i held up with mustangs, if that serves as proof)
/end rant, bleh, I need sleep

Well, at least its not losing any power and it seems that a few people have the same problem (if it is a problem). Like someone said, it could be the air flow. Either way, I know that a dealer here will be hesitant to fix somethng that you can barely feel or see. I'm not too worried about it cuz I accelerate slowly through the RPMs and then do it again faster, I don't hear it. Strange.

Could be pinging. Using premium gas?
True story: I owned an older Mustang that ONLY ran on premium. If I put any lower octane in it would ping like crazy. Every so often I would buy premium gas and the engine would ping. This told me that the gas station was "watering down" its premium with regular - crooks.

Went to the dealership...they said it could be the gas I'm getting from my particular gas station, and to empty the tank out and try 2 tanks from a better gas station they recommended (mobil), and see how that works out. They said even though it's 93 octane, it could still be bad gas.
They had the same problem with another rx8 in the area, and they drained the tank, put it premium gas and it was fine.
Watering down their premium? Interesting.

So does yours sound like paper rattling? That's the best metaphor that I can think of cuz its not as loud as marbles in a blender. Anyway, thank for the info!!

SlowLude, you're getting this sound with or without a CEL? Real detonation ought to throw a CEL.

Yep, mine exhibits the same behavior. If I romp on it, (and hear the rattle)
then later in the drive romp on it again, the rattle diminishes or disappears.
Maybe the PCM retards the timing from the onset of pinging until the drivers foot gets lazy again for a period of time. However, I don't care for the noise at all, and probably either does the engine!

Probably will take it in to the dealer and have them check, while they are removing the massive door ding I got on Saturday. Kill, kill, kill the guy who dinged my door! Argh...feel bad inside like puppy died. Kill, kill, kill the guy!

I think the dealer replaced them as part of the new car prep when I bought the car. Gonna check the paperwork. If they were changed, is this normal for new cars with 1400 miles on new plugs?
