Kia Sportage intermitent start problem

Car: Kia Sportage
Variant: 1.6
Model Year: 2021

Sometimes on start up the car does not fire on all 4. A shut off and restart and problem gone and runs and pulls fine. Happens on a cold engine. I have run a can of jet cleaner through as a precaution but, still happens. Verry intermitent problem so not overly concerned. Would like it gone all the same. Thanks.

Depends on mileage and services carried out . Would check / replace plugs , check clean MAF sensor before getting too involved

Or could also be the engine coolant temp sensor which lets the ECU know among other things , how much fuel needed I.E , more fuel on cold start , like operating the choke on old cars

After a restart it"s fine. Dont believe it has a MAF sensor, only a MAP. No engine management light during the blip or after ( maybe a clue there!) Also i believe it effects more than one cilinder as it bounces about a bit. Thanks.
