Rough Idle on Cold start, Video attached.
Hello All!
I’ve a very rough idle on cold starts only. No check engine light, but almost sounds like it’s misfiring then settles after a few seconds. I’ve attached a clip of it, although pretty poor quality.
I’ve changed, plugs, coils and purge valves, it’s also just been serviced.
2015 car with 66k Kms and no mods.
Anyone have any ideas as to what this could be? Many thanks!
