I think I found my problem..

The #5 spark plug was very very loose. This could definitally cause detonation correct? God dammit...

loose enough to let unmetered air in?

Crap...just drove the car, still there. Arg. sorry for starting two threads.

A loose spark plug wire will not cause detonation.

Think about it; pinging is basically caused by too much air and not enough fuel. How could a spark plug not firing cause this?

My PCV valve has not been changed since I have recevied this car, and the previous owner kept crappy care. Could this cause it?

Well my brakes are really ****ty and when I brake hard the brake light comes on, maybe there is aleak in the brake booster hose or something.

Does it look like there is a gasket here? I mean at the top, its sticking out at the bottom.

Yargh...I've never heard of someone having a loose spark plug before. I guess that's why it didn't register.
