I would recommend that you have your Ignition Timing checked…a service you can get at the dealer…do you valve adjustment and have your throttle cable adjusted if needed.
Other things to look at are the Fast Idle valve and the EACV…
I did all this and the problem was minimized considerably.

It was the tps sensor.
I have a similair problem as you guys just not as bad. When i hold down the gas petal very little, about 0.2-0.3% (I have a VAFC so i know), the rpm drops about 100-200 and hesistates for about 1-2 seconds and then revs up. Funny thing is, this only happens when i am on an uphill slope. I had the same problem with my 1992 mazda mpv and had it fixed at a shop. I just forgot what is was.
