smoke comes out in bursts from moving object I am making a firework with a fuse to look like a S, and when i bake the flame, it is OK at first while the firework is not moving very fast, but when the firework speeds up, the flame comes out in bursts but I want it to come out continuously.

It looks fine at the beginning while not going too fast,


But when it catches speed the flame comes out in bursts

You need to use your flow object's sampling subframes.
Select the object, go in the physics Properties tab and change the Sampling Subframes value.

It can be animated but you need to know this : more subframes = more processing time
