manifold cleaning

Friends, have you heard of a manifold cleaning before, told a friend a mechanic, I wonder if we have an institution in our cars how to clean ..

I have never heard of it, it is not easy to click, maybe it meant catalyst

So what does the catalyst do and how do we know it is clogged.

It helps to burn some harmful gases that the engine burns without burning
good to clean occasionally 100-150 thousand

Pedal Electronic is connected to a potentiometer. According to the data received, the butterfly engine gives the necessary movement. It is too early for the gasoline floor of the vehicle.
