My Peugeot 405 stops ..............

BUENAAAASSSSSSSSSSSSSSSSSSS

I have a peugeot 405 gasoline, after making a highway journey, generally, when I leave it and I have to stop in a ceda or traffic light or roundabout ....... you get off and end up stopping the car.
Data: I just changed spark plugs and gasoline filter

What can happen?

Greetings and thank you very much

You already tried that the engine would calibrate you, and adjusted the minimum, the same happened to me after I did a tune up and it was that the mechanic left it badly adjusted

I don't know what is that of Tune Up ............. the thing is that I started lazy
with very low idle and sometimes it went out. That's why I changed the spark plugs
and gasoline filter so that it would start better, but keep doing
the same .....

Thank you very much!

What year is your Peugeot if you have IAC I recommend checking it is regulating the relative, your car is turned off because the release is very low.

What you can do is regulate the aceration in idle of your vehicle
