Tracie, have you considered a rattle from the exhaust hitting something? If
the exhaust plumbing sits close enough, it will rattle when the engine rpm
is just right to resonate. Same thing will cause the heat shield on the
cat to buzz under specific conditions. Given the RPM range you describe,
I'd be looking for mechanical noise as well as for ping.

The definitive answer about ping would be a full tank of high test gas under
identical conditions. No noise, likely ping. Noise still there, rattle
time.

I did get it at the same station, but I don't know if they have
switched to winter blend yet. I will try going to a different station
to see if the car still does this. I don't know if this makes any
difference, but I did notice it since the day I drove it off the lot
(bought it brand new with 74 miles on her).

If the exhaust is sitting close enough, is that something I can re-
route, or do you just live with it? It isn't anything I can't live
with. I was just curious as to what is causing the noise. But like I
said in the earlier post, I DO remember hearing it even with the stock
tires since the day I drove her off the lot brand new. It may even be
characteristic of the type of engine that is in it (NSG 370?) or
something like that. I'll check underneath to see if there is
anything loose that may be rattling.

The only other noise that she makes that I can't figure out is the
single pop she makes when turning corners (left ONLY), or once in a
while when going straight. I have a feeling it has something to do
with the steering colum. I distinctly hear it up front towards the
center. She doesn't do it all the time, only when feels like it.
Other than that (and the possible engine noise -- if not normal), she
runs like a dream.
