a neck snapper, dash pot effect.
the J18 is same, engine, (the mounts on the block might be different, the CKP sensor wildly different and the ECU to match it.) and new CMP on cam left rear.
I do not know the Swift, ECU at all, never used one.
but is quite different.
the j20 engine parts swap, the j20 is stroked j18 engine. good to know for finding parts, infact some SPORTS are upgraded to j20 and the ECU seems happy, (CKP changed out)
J20 has new head, for chamber changes, CC sizes.
this is the ckp horror... (even the G16 is different , same year, on Esteem. a real hail puller, with CKP errors endless, until eyes see it.)

the newer J20B has lots of changes, (above is J20A,96.97)
the key factor for Next snap is DP controls.
what make it work.
sure TPS below 1v, (the FSM will even telly when the DTC for TPS low fails. in the pages covering DTCs. on that Swift)
my guess is the engine must be hot, over 150f ,180 to 200 f best.
the motor is on the TV ?
the Suzuki engines , even swift, sue different throttle bodies, in different countries, due to lower costs needs or smog rules of that country (laws)
as does TPS calibration needs or if needed at all (autocal on newer cars) but i digress.... but 2001 cars are very difffent from
our J18 uses the ISC to do dashpot effect. (all hot water control-ed IAC are retracted)
2001 US/CDA spec Suzuki Esteem with the J18 MPFI engine. (1999 to 2002 generation it is) what transmission?
the engine has a serial mark.
26 ECUs offered that generation, but 2001 , is just 4 ECU (usa) 2 are A/T and 2 are MT the VIN is change (serial end numbers) 15204404~ is NEW ecu for M/t and A/t
why Ive no clue. there.
the IAC is an electric motor, and does not open the TV at all its a motor controlled, air valve, that mounts to the plenum , simular to the EGR valve. motor operated too.
this valve can stick but that causes high RPM. not low. and snap.
my guess wrong ECU?
id need VIN and transmission type to say ECU p/n, and can.
that Throttle body ,has water hose, and a IAC thermal valve of some kind and must retract if not the ECU will get confused. id look here first.
the TB only has 1 part sold , the TPS (by suz)
the MAF inside is not sold by Suzuki only by 3rd party aftermarket Hitachi. it can fail. or need cleaning.
are you missing DTC code P1700 (does your scan tool do P1xxx codes , factory codes? at all?)
in the year 2001 suzuki , used year code 1, (2000 = Y) so engine code, is J181nnnnnnn the 1 means year 2001. nnnnnn is raw serial. that is one way to find engine swaps , the codes.
my guess is the ECU is confused.
do to wrong inputs somewhere.
is engine ECU in closed loop mode, before and after throttle cut, hot engine?
is hot idle at spec.
if you turn on head lamps +heat fan same time , does rpm hot old at 800RPM or fall fast? ISC(iac electric) regulation must work or DP will not.
The DP effect is TPS triggered, my guess below 1v. (what ever the manual says for TPS error thresholds , that is it)
if hot idle speeds or regulation fails, i do that first fix.
i think the IAC (motor) is stuck.
when at cruise, the ECU may shut it down due to unused status cruising, (IDK) then as you cut the throttle in gear, the engine brakes you, but the ECU then open this IAC motor to do DP effect.
This is very complex here in the software, my jeep is even more complex it memorizes cold starts and knows where to open the valve, for any cold start temp.
and my old 4 liter loved to stick the ISC (motor IAC) , until my cure. (Russian, gun lube from Siberia)(sprays on , feels like teflon fry pan coating) magic stuff.
the reason the old jeep failed is the motor was to small in the IAC. (design error)
cheers, to you.
