knock and timing pull under no boost ?

[Vicious_mole]

there is a link for a spread sheet off google that i loaded this morning

Google Docs - run02272008-5

you can see the timing just fall the a/f ration is good low tps no boost ect what would cause the timing to fall like that ? bad knock sensor?, all the knock logged is at cruise spees with the cruise control on


the bad knocking start at timestamp : 241524080 - 246576880

but you can see other knock on the spreadsheet as well just thats the worst part

Anyone?

I'm getting the same thing, vacuum knock... Bad sensor, loose, I don't know. But it happens the most when the engine isn't fully warmed up. It lessons if not goes away after it's a running temp. I'd like to see other DSM'rs inputs on this.
