A strange phenomenon when you give gas There is something strange happening with the car's RPM when standing still... I give one press on the gas, after which the rpm goes up and down and then jumps again by itself, what could cause this?

You already asked about bad gas mileage and received detailed answers.
Live data needs to be analyzed to see what's causing the issues you're experiencing. If you are unable to do that yourself take the car to a good independent mechanic.
The EVAP system is less related to the phenomenon here...
And likewise, it shouldn't have such an unusual effect on fuel consumption...
What do you mean?
That I have too many problems?
Fix your EVAP issue.
It means "fix the EVAP issue" first.. so you can move forward.
I understand,
I have since managed to change the fuel filter and the car behaves much better, the engine is much more alert and powerful.
Regarding the EVAP, I got to look at my CANISTER and it looks a little different from what they sent me, so I need to dig deeper and locate the problem...
Speaking of which can I use a compressor with air pressure in the EVAP system?
And that's how to know if there's something blocking it or if I might cause damage?
In addition, the fuel filter caused the phenomenon of the rpm jump to disappear.
Now if I give a touch of the gas when the car is stationary the rpm goes up and then goes down relatively slowly which I'm not sure is good either...
many things could cause it. Could be a problem between the accelerator pedal and throttle servo.
Take it to a mechanic who can look at your live diagnostic data to find the cause.
Ok that's what I'll do.
Could it also be injectors that drip fuel?
I also have high fuel consumption (the value on the display is incorrect)

Fix your EVAP issue. You have too many irons in the fire.

I just take care of the most serious to the least serious...

You'll cause damage. Don't use an air compressor on an EVAP system because they use low pressures. You should be able to find an inexpressive smoke machine on Amazon. It's a good investment because it's a handy tool for finding vacuum leaks also.

Not sure if this an issue. If the rpm drop is very slow, I might be concerned. You have to address the EVAP issues first because that could easily cause the noticeable lag.
I will try to work on it.
By the way, today I was in the car and the phenomenon that the RPM jumps even after I pressed return
