just thought i'd bump this thread because something else occurred to me, and also it wasn't clear whether or not OP got his situation resolved.
a lack of torque definitely creates a tendency to be sluggish at low RPM under load, but the car shouldn't bog if it's being revved in neutral.
the reason this occurred to me: i have been working on my heel/toe-ing for a while now, and have become fairly proficient; i had been noticing, though, that i was more and more often missing smooth downshifts, because the revs weren't rising at the same time they had in the past. i'm not sure i'm doing a great job explaining this, but basically...say i'm in 3rd gear, slowing for a corner, and brake/clutch/apply throttle to match the revs. instead of the revs immediately climbing when i would apply throttle, they would dip first (bog, drop off, what-have-you), and i would miss a smooth shift.
since my car had a CEL on for a while for the TPS, but it went off on its own, i'm guessing that there is a range of operation that's allowable; my car was borderline, and so showed a faulty TPS sometimes, and then an ever so slight change brought it back into the range of acceptable, but still my condition existed.
which means...it appears possible that the TPS could be borderline faulty without throwing the code.
that is all.
thoughts, skip?

When I was stroked(non-sexual this time), we initially had some fuel delivery issues, whether it be from overload or whatever, but I would lift for a kink and reapply full throttle. The car would hang in decel. Not good on a downhill, slightly-off-camber turn- you need to be planted via throttle(loading one side of the car).I would have to lift a second time and reapply throttle to clear the problem or shift to another gear all together. That was a tuning problem and was worked out.
