or at least say is it 8valve or 16v engine G16A or B?
2 radically different answers on those 2 engine, TBI and MPI are not the same at all.
sorry.
top cause (wild guessing reality) is MPI engine, IAC thermal idle valve below the throttle body (side draft) is stuck open and bad, super common.
same goes for 8v TBI the IAC in the base of the down draft TBI is bad. stuck open.
other causes.
8v, lots of vacuum leans RPM goes why high. with full power
on 16v, it uses MAF and no MAP so a vacuum leak makes it go lean and slows down. (running hot normal 180f)
but the 16v if on cold start warm up mode, Not told you, when it happens but is cold it is now in ENRICH mode and when cold vacuum leaks cause faster idle until hot.

- what car
- what engine
- what fueling system is there, of many world wide suzuki, in the 90s.
- what mods
