I used my bluetooth headset, and then I could hear what you are talking about. I don't think this is pinging. It sounds valve related. I've only heard of pinging like this on really hard acceleration, and you don't seem to be really nailing it...2fs2ns wrote:I'll look into the knock sensor, I'm not sure what that involves.
With 93 octane it still pings pretty good on moderate accelleration. You really have to baby it to keep it from pinging. I'm running another injector cleaner bottle through it now, still pinging.
Not sure if the audio in this video clip is any better...

Maybe a leaky exhaust manifold gasket? I dunno man. I'd get it up on a hoist ASAP so you could at least rule out the simple and easy stuff.2fs2ns wrote:I seafoamed it tonight via the master cylinder vacuum line.

It doesn't sound like the front end, as a matter of fact it sounds like it's coming towards the rear of the engine, low. Could this possibly be from some kind of exhaust issue?? Could I be hearing something you normally just wouldn't? When I'm driving with the window down it almost sounds like it's right beneath me.
