Timbosabe Did you ever figure this out? my 95 4runner does the exact same thing!

(as other guy described "falls flat on its face") If you hold the accelerator down it eventually starts taking off at its own pace. Or he could be on the freeway driving fine and he hits the pedal to pass, and nothing happens. If cruise control is set on 70, then it might drop to 55 all by itself. It is throwing no codes whatsoever, so every shop says, if it's throwing no codes, then we can't fix it. Colder weather, it almost always runs great but with warmer weather it acts up much sooner. So is it possible it could be the mass air flow sensor...?
