Nothing is jumping out to me, long term fuel trim might be a little high, but still single digits, and it happens some at idle.....does that o2 (o2s11)voltage change high/low past .450mv?

I could plug in a scanner to mine for reference #'s from a different engine to help confirm my guesses, first question that comes to mind is if that is a set of readings from idle with NO throttle input.

TPS value at the top seems high for foot off the pedal.

OK, quick check showed #'s like yours where I was unsure, had 17.6% at idle.

Calc. load & rpm are similar as well.

Any others of interest?

Ign. advance on my Duratec is at 5 when idling, jumps off that to 20's & 30's as soon as the throttle is advanced at all. (depending on RPM)
