Mazda Mazda 6 2020 Automatic Gasoline I have a problem with my 2020 Mazda 6 full option car. The mileage is 277,000 km. If anyone knows a solution, please help me via private message. The car's throttle, air sensor, and accelerator sensor have been cleaned. When I turn off the car and turn it back on, the problem disappears as if nothing was wrong. The car experiences this problem: it doesn't accept acceleration smoothly, sometimes sputtering, and sometimes the issue appears as soon as I start it. I ran a computer diagnostic. Some people tell me to change the accelerator pedal, some say to change the engine computer, some say to do an update, and some say to do a tune-up, even though I just replaced the battery and spark plugs, and the problem existed before that. And I haven't found a solution yet.
