Why does the engine idle intermittently with gasping?

[SanMakayla]

Reasons for unstable engine idling and intermittent gasping: 1. The air-fuel mixture is too rich or too lean, resulting in incomplete combustion. 2. Low ignition voltage, insufficient energy, or leaking high-voltage wires. 3. Fuel system pressure is too low. 4. Poor fuel injector performance, with uneven fuel injection among cylinders. 5. Incorrect sensor signals causing a mismatch between the engine control unit's fuel injection signals and actual operating conditions. For rough idling, shaking instability, and gasping, follow these inspection steps: 1. Check for fault codes; if present, inspect according to the fault code content and determine idle speed settings as needed. 2. Check if the cylinder high-voltage wires are incorrectly connected or if any cylinder is not functioning. 3. Verify the proper operation of the idle control valve and ensure the idle air bypass passage is unobstructed.
