The Mazda engineers must have a different strategy/program??? Not sure? My 98 Mystique LS sometimes will surge but not that bad. Could be the combination of parts associated with controlling idle/ac on, is just enough tolerance difference. I'm sure to try and find the info would be near impossible unless we knew the sources. Could get a Mitchells manuals and try to compare, but it's probably an apples & oranges thing?

I've always had this hang-up, just knowing how it works wasn't enough, I always like to know the details & why.
