Tiburon 97 cold morning misses cant go pass 2000,3000rpm.idles till warm but still misses

Possible coolant temperature sensor. It relays info to PCM which in turn regulates fuel needed for different engine temperatures. If sensor is faulty, it may be telling PCM that engine is already warm, when it's actually cold and needs a richer fuel mixture.

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

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

your iac or idle air control needs cleaning. the idle valve is probably stuck and not letting engine idle right.

easy way to strat is check all your spark plugs.jeeps are also known for the crank positioning sensors going bad.another possibility is the oxygen sensor

Ford 2004 6.0, Driving down road seams like when it starts warming up it starts Missing or accelerating,jerking,as long as you keep the acceleration it seems to work as soon as you level it out it starts missing,even dies at stoping sometimes...Changed fuel filter, put fuel additive in tank still missing,HELP

replace main relay

check the coolant
thermostat are cheap and easy to fix

have the fault codes read to get the problem area

crankcase sensor, located behind starter on 3.5
