Hello lala. I ain't no expert, but that seems like a throttle body problem. About the only thing that these little girls can regularly suffer from. I hope others jump in and identify it for you, there are some smart boys and girls on here who will help I'm sure.
The TB ( throttle body) seems to play up do to lack of regular oil changes, there is a trick with a bit of solder which can improve this problem, others will say how.
You can also source these quite easily on ebay, I did, and solved a similar problem. Check the numbers on the TB before you buy as there are different ones around. If you are stuck, I have one, if it matches yours you can have for the postage.
I bought in haste and found out there were different ones - me bad. Hope you get it sorted, you're in the right place.
