@6:12 😬 Btw, I love the videos. I recently got a daily driver/project Mazda 6 estate (also in the UK) too. It's done quite a bit of mileage so having to do odd little bits here and there on it, just like you!
Generally the inside is rust free, but the front and back subframes underneath, woah, quite rusty. I really need to get down there, clean, treat and paint. Back then, we used to just spray engine oil under cars/vans 😅
Thank you for your videos on the Mazda 6 GH. I have the same problems as you. You started with the EGR valve. It was a good idea because it pointed out the problems. Now you have replaced the two O2 sensors. Do you think that all the problems came from the two sensors only? If so, I will start with that. What do you think?
👍 You are welcome. Going through all of that, I suspect that the first o2 sensor was the main trouble maker ( The one closer to engine). I still haven't checked the situation with fuel pump and the filter, that could be one of the causes
@@KlavsX_ I also have the fuel filter on my list. I will order a new filter and the O2 sensors today. Then I'll have a look. The air mass sensor would also be a possibility. I hope that's the right word in English. I mean the sensor at the top of the air filter, you can try cleaning it.
I will order a new fuel pump assembly and filter. As I have no idea if the pump has been changed or not. MAF sensor - mass air flow sensor, you are correct, but MAF problems throw a error code on the dashboard, and car will 100% idle really rough

👍 Awesome, have fun with the car, and check the trunk / boot for rust under carpets and the jack

Did you buy expensive ngk sensor od cheaper ones?
I got a cheaper one, not the cheapest. Somewhere in the middle, if cheap is 60 and expensive is 140, I got my one for 80
Where did you buy this 4 pin rear bank2 sensor? I can not find it anywhere. My mazda is 2010 same as yours, 2.0 petrol.
I got my one on eBay.
How much I have found the best ways are eBay or from Mazda directly. But it will cost quiet a lot
