Hello and welcome to JA!!!

Billy :

I'm Billy and i will help you with this.

Billy :

Cold start defects can be caused by multiple reasons, basically everything that weakens the engine a bit will show on cold start, as at this stage the engine will be barely operational.

Billy :

The main things to check on a cold start problem (stuttering until engine is warm), are the following:

Billy :

- spark plugs.

Billy :

- coil packs.

Billy :

- clean throttle body

Billy :

For the first thing, you have to remove and check/replace if necessary the spark plugs, as they could trigger same symptoms you are having.

Billy :

Now to check coil packs, you can spray them with a bit of water, while engine is running and look for changes in idle, or even visible spark coming out of the coil

Billy :

To clean throttle body, you will have to remove air filter box and hoses coming to throttle, and then clean thoroughly using WD40 and a toothbrush.

Billy :

Having done the following, your problem will mostly be resolved (i think from step 1: spark plugs)
