If you remember, I had a problem with removing the catalyst without turning on the engine malfunction light.
I wanted to share with you how
Firstly, the floor was dismantled without damaging the sensors and a new piece was cut to keep the pressure called flange tomorrow, corresponding to the upper section of the floor. And I have been using it for a long time and the malfunction light did not go on as far as I can.
and lastly, I did not feel any drowsiness in the lower ages, but the comfort of the car is obvious.
