I've started noticing a jerking sensation in the powertrain, accompanied by sudden drops in RPM and occasional sputtering before the vehicle returns to normal operation. The diagnostic trouble codes detected are P1280 and P0603. I found a brief explanation online but need more detailed information on potential solutions.

Have you installed an aftermarket tuner? P1280 is commonly linked to tuning modifications. Please confirm. Additionally, inspect the ICP (Injection Control Pressure) sensor for proper installation, ensure it's free from corrosion, and verify that all wiring connections are secure and intact. For P0600, a common cause includes a disconnected battery or a dead battery—try reconnecting or replacing the battery if necessary.
