2005 suzuki liana.1.8lt gas. australia. engine bogs down on 1500rpm, no accelleration, i have changed the coil packs, what else could cause this issue. thanks.

It is possible that there is an issue with the transmission or the differential in your Suzuki Liana. It is also possible that there is a problem with the engine itself, or with the fuel system. I would recommend having a mechanic diagnose the problem in order to determine the cause and recommend the necessary repairs. It is also possible that the issue could be related to the tires or the suspension, so these should also be checked.

check fluid level --water pump -thermostat-cooling fans

Could possibly be your Air Flow Sensor... run a code check on CPU - check fuel pump/filter for blockages or malfunction also check spark

no year car, no country no engines stated, what joy , PAR here.
lots of codes. a barrage of them.
first off i bet you didnt clear them (yes write them down thanks)
then see if they call come back.
this is SOP.
egr is 400
301 is misfire #1
304 is misfire #4
300 is random misfire, so all 4 do.
134 Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 1 Sensor 1
340 is serious. means
Camshaft Position (CMP) Sensor Circuit
btw all but 400 is caused by 340

but since you posted with no facts, we cant help you can we.
each engine is different ,totally different.
you posted to a USA form that has no such car

The Suzuki Aerio (called the Liana - Life In A New Age - in )

and 7 engines.
all very different.

only this man can guess , engine, and he retired long ago
smart guy him

Carnac,knows all and can guess, and always be right. !!!
but he be off line now. RIP Johnny. Loved him.

no year, stated.
welcome to USA forum
the forum and country with no M18a,
this Liana name is only used, in
called the Liana - Life In A New Age - in China, Pakistan, Europe, Israel, South Asia, Taiwan and Australia)

you never said which country, so cant help you could anyone.
really
go to your suzuki dealer in your country and ask this.

USA runs a J20b engine, on the Aerio (our name for same car class)

welcome to the USA forum , is your car USA.
no.
my guess is it has the M16a engine
see bottom left CKP #5
The M class engines , its on the PULLEY side
and facing said pulleys, (regardless of car it is)
its to the right of the pulley
that means the crank tone (teeth) wheel is behind said pulley on end of crank shaft.

we do have swifts here with m15 or M16
here is the CKp sensor on the M15

The thermostat is in the thermostat housing where the water hose hooks up to the radiator, if you don't know where that is take it to a dealer or Auto Parts store.

pretend we are blind.
what country.??
06, Liana.
what engine, Gas or Diesel???
there are 2 systems. OBD1 and OBD2
the hood stickers usually tell you which it is. (obd2 certified)
if car is OBD2 cert then any cheap but new scan tool works.
if car is USA car the OBD2 port is near the knees, 16pins
the spec, call out 1meter from steering shaft center. USA spec.
OBD2 is a USA spec. so...... where are you......

see here the car and all the variants.
see why we dont know, until you say so.
