    “Unstable Engine Performance and High LTFT1 Reading Issue”

    As soon as I start the car, it begins to shake and alternates between stabilizing and shaking continuously. When I connected it to the OBD2 , I found that the Long Term Fuel Trim (LTFT1) percentage was higher than the others, as shown in the image. What’s the solution?
