Car seems to be sort of choking

[tyrone_yaris]

Hi,

In the mornings when I switch on the ignition the car seems to be sort of chocking for a few seconds and then the engine runs fine. Only happens in the mornings or in the evenings after work when the car is parked overnight or for a long time say 7-8 hrs.

Otherwise the ignition starts normally in between.

It's a Toyota Belta sedan called a Yaris sedan there. Haven't check the spark plugs as yet though. Battery is fine.
