What does it mean that there is a fuel correction on the automobile tester?

In this case, it is usually to replace the ignition coil and cylinder spark plug, but that is only a very common problem. For you, you can do this. Too high or too low concentration of mixed gas will affect the air intake. Whether the fuel injection pulse width is normal, whether there is a problem with oxygen sensor heating, and whether there is a conflict between ignition correction and fuel injection correction. Whether the throttle position sensor signal is reliable. But many times gasoline will cause such a situation (fuel filter). And whether the throttle is electronic. . . Is this car automatic or manual? If it is automatic, wheel speed sensor, gearbox oil temperature sensor and output shaft sensor will all affect it. But your situation has a lot to do with gasoline and mixture. When excluding, delimit the execution area.
