I have 1991 8 valve 5spd and mine does same, but rpm being 2300 - 2500. In addition to that hot idle is not maintained correctly. My hot idle is about 800 rpm, but when I turn on high beams, blower full, seat warmer etc it drops to 600 rpm, so ecu is not correcting it.
Mine is most probably fucked by some carburetor guy doing his magic to fuel injection without understanding how the fuel injection works.
Fixkick gave me some info about it in following post: https://fixkick.com/forum/thread-vitara-...5#pid13045
Those actions will not work 1:1 with your newer car, but maybe it gives some points to try to check. And mine does it sill after fixing all vacuum leaks. Look especially where he says:
> this is the TPS idle switch set wrong. the ISC must go off line with right foot pressed, on your car it is set wrong, and the ISC is wrongly active fighting the right foot actions.
