I had the same problem with my 92 and thought it was heat soak, as the problem did not develop until the engine warmed up. My theory lies in the timing. We know the engine has an inherent problem with the VTC's, in that they stop working, make noise, and ultimately fail to do their job, which revolves around automatic timing adjustment.
Roseken, a writer on the bbs, discovered that the problem was timing related. I think I recall him hypothesizing that once the engine went into open loop, is when the "sluggishness" began, not necessarily from a build up of heat. Still in disbelief that it would be timing, I turned my crank angle sensor slightly to the right and advanced the timing. The result was twofold, the terrible acceleration was gone! I took it out and romped around with it, as the car was fun again. An easy, five minute fix is all it took. n1. We had guys replace coils, try a new TPS, MAF, none of which fixed the problem.
I'd really like to see you turn the crank angle sensor just a little bit to the right and observe the effect. Let me know what you think. I'm almost sure your problem mirrored mine and revolves around retarded timing because of failed VTC's.
n1: Keep in mind I had the rewire done all along. I'm not sure the effect of advancing the timing manually on VTC's that partially work. I would only manually adjust after doing the rewire. [/QUOTE]
