@ericalzablon: When the hose shows a crack, air may enter that has not been measured by the MAF sensor. This alters the air-fuel mixture and can cause unstable acceleration, increased RPM, revolutions, jerks, or even engine shutdown. The ECM tries to compensate for this condition by adjusting fuel and controlling acceleration. Recommended test: With the engine off, inspect the hose by gently bending its folds to identify hidden cracks, especially in the lower part. Then, perform a smoke test in the intake system to confirm the leak. With the scanner, you can check the STFT and LTFT fuel adjustments; high positive values in acceleration that decrease when accelerating may support the suspicion of unmeasured air. #fyp #viral #tiktok
