100 Octane

Post injector, coils and plugs replacement

At full load, the car drives normally and there are no issues. However, under partial load, the car starts jerking very hard. When this happens, the accelerator pedal becomes unresponsive — if we try to increase throttle, there is no reaction from the engine. When we release the accelerator, the jerking immediately stops. We tested this behavior on Stage 1 and Stage 2, and the problem occurs on both. After flashing back to Stage 0, the issue disappears completely. Please review the attached logs and let us know what could be causing this problem.
