Hello together, I have the problem with my MAZDA 626 Bj 99, 145000km, only during the cold season, when the temperature falls below 0°C. The ignition works without problems. But only in idle I notice that the fuel is not assumed. I can not reach higher speed On the exhaust I hear noises as if the exhaust leaks. When starting I have to switch into the first meters into the second gear, I can pass through, but the car stutters and can be I have to switch to the 3rd gear (up to max. 30km/h) and then switch to the 4th gear, and reach a maximum speed of approx. 40km/h with a lot of stutter. 🙁 When I pass through, nothing happens. Only when I drive several km, depends on how cold it is, (at -5°C to 25 km) the car slowly gets into normal condition. And then the problem is solved. In the other seasons I have no problem at all. m, I am very satisfied with my MAZDA. Yes, now my question, where could the problem be? Thank you for the answers
