5.0 spark knock under hard acceleration

[johnmcgt]

Thanks for all the great replies.

Are 5 & 6 the only two that need to be seperated????
I do not have a chip, yes the spout is back in. My GT has 108,000 mi on it, when I got it wires,cap,rotor, fuel fltr were all original, I would guess O2's are also.
I have a scan tool and no codes are being sent.
I have heard of putting a 180 thermostat in, what is the factory one??? I live in Florida, it has already been 95+ deg with 90% humidity. Not the best for performance.
I would feel better if I could get rid of this problem, sounds like I am not the only one. Has anyone had experience with the fuel system. A person at work has a GN, he put a new fuel pump & regulator and said this solved a lot of his problems.(I told him the only problem not solved is it' still a buick, HAHA)
About gears, what will an AODE rpm be at say 60 mph??

Thanks for all the great help,

I hope all this talk solves everyones problem.
