Peugeot 306 shaking misfire when engine warms up

In my 1.6 Xn Peugeot 306 vehicle, both petrol and lpg misfire and shake. When you turn off the ignition and wait for a while, it seems to get better, but when the temperature indicator sees 90, it shakes and misfires again. Does anyone know why he does this? Friction noise coming from the exhaust (possibly the catalyst) now

good evening, my master, I have the same problem in my 206 car, when it's cold, nothing happens, when it's hot, there's a fuss from the exhaust, stuttering, cluttering, later opening, can you tell me if you solved the problem?

Unfortunately, I haven't found the solution yet, let's see, I hope a master who understands the vehicle I will tow the industry with a tow truck and I will inform you when I reach the solution.

Get well soon, I hope it won't cost much, according to my research, there are those who say that the temperature sensor does not do anything when the car is cold, it is said that when it gets hot, it misfires because it cannot adjust the gas or gasoline, but I do not know how accurate it is, I hope it will be solved soon, my master.

by the way, if you are in ankara, there is orsel motors in my ostume just to take care of the peugeot group, I took my 106 truck to this man, he said the engine will be built 3.5 I went on the advice of the master, this man only solved it from a hose crack.
