Thank you for all your answers! Good to know that my lambda sensors are different. I will have to check them. I did the cleaning. White smoke was coming out of my exhaust but nothing bad really happened. My car didn't stall in the process. Obviously i didn't pass any emmision test right after everything failed. Yesterday i made about 100 km and checked my engine. There was no errors and i passed all emmision tests. I think it really worked. At least for now. And my car seems to have more acceleration but it could be placebo...

I couldn't do anything yestarday it was raining. I will try today and update. Can i have 1 more question about sensors? So there are 2 lambda sensors, one before and after the cat. My question is are those 2 sensors physicaly identical? Do i have to buy a specific lambda sensor for pre cat or just any that fits my car and plug it in?

Last time i checked it was 90 C. I think it's always on this level. But i will do some tests when i get home. I should do the cleaning today so i will update my post. Thanks for your answers.

Yes im trying to adress the emissions problem. I will try to explain. OBDII: P0130 heated oxygen sensor Skoda: Circuit closed loop bank 1 sensor 1 OBDII P0172 Skoda system too rich bank 1 Skoda: Fuel trim system rich bank 1 I get those errors when my car is warmed up. When it's cold i get no errors. Most of the times my ecu gives me only 1 p0172. I was driving my car few days ago and it stalled when changing gears. I couldn't start up my car for about a minute. My ecu gave me both errors and egr valve problem. When i was checking my emmission my catalyst didn't past the test. I had the same issue about 2 years ago. My car was randomly cutting off power when changing gears and i couldnt start it up again. I had to wait a while. My dad cleaned the throttle, catalyst and changed the egr valve. It worked good. I want to try cleaning my catalyst because i cant get pass emission test. And im afraid that my car will start to stall again randomly. When my car is cold everything is fine.

Hello. Im an owner of skoda fabia 1 1.2 htp. Can i remove an engine cover and start my car. Is it safe? There are two hoses connected to the cover and engine and connection to throtle. Looks like this https://images.app.goo.gl/iuUY9nGJv2Kn7os59 . I want to use a catalyst cleaner and spray it into the throttle for some cleaning. Can i take off the cover, unplug hoses and start my engine without worry?
