in further discussion of the shuddering/fluttering effect i am experiencing at WOT (and a few others), i have a log of the A/F,rpm,TP at the time of when it was happenning.

I noticed the A/F was a lean condition for the first few seconds after mashing the pedal. So maybe not enough fuel getting there? Anyways, anyone intrested have a look!

here

they are the #3 set and the DJL file can be viewed by the widebandcommander software at widebandcommander.com or you can check the text file.

Also, is 11's later on in the A/F too rich? This datalog was done starting from a roll at approx 45mph

 

Anywhere in the 11s is fine. And in my (never to be humble) opinion is a little fat if your wanting to go fast.

Rich

 

Is this indicative of a clogged fuel filter? Just curious.

 

Lots of info here on this type of problem. Do a search and you'll see for yourself. My bet is you have a bad coil pack.

That surely will shut you down at WOT.
