Trying to figure out knock

[Robjob]

Having this knock issue, and for the life of me I can't figure it out. The tps looks a little suspect to me but, tell me what you think.

I'm not sure what you tried to attach but it didn't work

I seem to be having this problem where I can’t upload the files anywhere

 

[pontiacgp]

what kind of file were you trying to up load

 

[Robjob]

I was trying to upload a dat file off the pl. It was a run I did yesterday about 73 seconds long

 

[pontiacgp]

wouldn't you have to export that to a spreadsheet?

 

[Robjob]

I don’t know, when I posted to turbotweak in the past all I had to do is upload the file.

 

[pontiacgp]

you might want to ask GP403 about it

Dude, this isn't a "Turbo Buick" specific forum. You need to go to turbobuick.com or ihadav8.com for most folks to even know what "PL" means (PowerLogger for those wondering).

That said your knock is usually attributable to fuel quality or quantity relative to air quality or quantity, or a mechanical issue - ie. something rattling away creating harmonic frequency interpreted by the ECM as "knock", or an internal/external issue/failure in the drive line.
