New suzuki swift gas pedal too light to press means over revving and stalling. Can I tighten it? How can I get some resistance behind the pedal

nice double post. and still no engine stated, nor country.
which engine,
5 engines world wide, this forum is USA forum
the enhanced 1.6L VVT? m16
you do know that many suzuki engines the covers and pan
are bolted on after a full RTV silicon gasket squirted on .
then cured, right? its it he FSM , ever seen a real FSM
a real suzuki factory service manual, sold at, "SUZUKI"???

is this what you have, now that you said VVT?
In October 2005, Suzuki launched the Sport version of the new Swift in Japan named SwiftRS, and in September 2006 the model was introduced in most European markets. Named "Swift Sport", it is powered by an enhanced M16A unit, a high-revving 1.6-litre, naturally aspirated DOHC VVT four-cylinder engine with an 11.1:1 compression ratio, high lift cams, forged pistons, and strengthened valve springs.

old post......

if the CEL glows, running. that meas there are DTC errors stored
on this very old car its a flash code covered in the FSM
or alldata.com
but switching off, you meant stalls. engine stalls, lights switch off.
the ECU on your car does magic things to prevent all stall.s
so if it does stall that means, its serious and when it does stall
the CEL COMES BACK on, at the stall that is NORMAL.
key on, not running , the CEL lamp is ECU self test passing.
89 swift.
what country?
which engine, of the 6 offered world wide.?
1.3L gas or diesel.?
is it the GTI? the first suzuki to have EFI?
its G13B high performance twin cam engine.??????
New Zealand
???
sold there till 1994
many other countries this name ended in 1988
as you can see below there were two very different 1.3 engine.
I think yours is the G13A, early.

1.0 L G10 (LP2) I3
1.0 L G10T (LS3) turbo I3
1.3 L G13A/BA (L72) 8V I4
1.3 L G13B/G13K 16V DOHC I4
1.5 L G15A 16V I4
1.6 L G16 16V I4

now the late answser
the #1 all time cause for old suzuki's to stall
is the EGR main valve stuck open
#2, idle is way below 800 rpm hot.
#3 never had a tune up, in last decade.
#4 fuel starvation.
there is test for each. ask

emission? you mean the SES or CEL? lamp ? check engine. or service engine,? lamp.
the car is under warranty for 8 years, take it in.
you could scan it with a scanner and if EVAP is failing
tighten the gas cap, reset the DTCs and lamp is now out.
and drive. top failure on all cars 1996 to now, is, loose gas cap.

possible clutch failure --sounds like clutch is slipping

Turn ignition on with engine not running and within 5 seconds fully press gas pedal to floor three times , the amber light will flash and system is reset, turn key off , next restart light will be off . If light is still on repeat steps.
Note . if this car has a DIC system this may not work but try it.D I C = digital information cluster.

its behind you glove box...no fuse no relay just a resister....probabley bad fan motor ? but check for 12volt first...

if i were you i would try a new air filter if no change go for a fieulfilter and then spark plugs and wires

the suzuki is an obdll system sorry need to have scanned with a scanner some auto stores such as auto zone/advanced auto do it for free check in ur area the code will give u a start point--sounds like fuel--possible some junk in bottom of gas tank got into fuel system--

evap purge valve is stuck closed you need a new one

has some of the fire wall sound deadner falling behind the pedal near the top where it mounts
