I had a nice reply all written out here, but I started looking more into your engine set-up and when I came back... everything was gone! Bummer! And I was hoping to bore everyone with another long usless post of my ponderings.

Short and sweat version...

Why do you think the fuel filter would cause the problems that your see? Seems as though everything is decent up until 5000 RPMs. From there is seems that whatever problem your having, becomes very noticable.

I was thinking that it might be the coil pack being weak.

Sorry for bugging on the questions. Just trying to learn what I can here and it seems like I have a some what similar issue with mine, although you have managed to obtain a fair improvment in your air/fuel ratio on the second set of graphs. What changes were made to obtain that?
