Seperate Every Random Second Event For Same Instance

So I have 9 sprites that has many variables such as engine speed, downforce, driver skill etc. In the event sheet I use event such as Every random 1-3 seconds to calculate something. The problem here is that random even is useless here as if let's say 1.5 were chosen from 1 to 3 range it would apply to all 9 sprites, but I want this to happen just to single sprite.

I tried using "For Each" however that doesnt work, and it only makes the event work for single sprite.

Try "picking" the sprite you want to change in the "condition" of the event that makes changes to instance variables.

Some tasks take time to complete. Just ask yourself if you want to develop something fast, or something of quality.

I don't know what you really mean, I added screenshot though,anyways I would be down of making all events seperatly for each sprite, however I don't want to because it would be really hard to edit anything and it's something I can't get right the first time.

Use the Timer behavior to set a period for each object.

Why multiple timers doesnt work at once ?

Not quite sure what you mean by that.

I made two timers, but only one work at the time.

In the On Timer trigger, you need to restart your timer with the same action that started it, to get a new random value.

how would I do that, I can only find "Start timer" or "Stop timer" event

Copy the "Start timer" line.

The "Start timer" is already copied in his screenshot. Also, the timer automatically restart itself if needed. I replicated the events and it seems to work fine on my end. Don't really know what's wrong...
