1 Answers
Engine multi-cylinder misfire causes: 1. Ignition failure, requiring inspection of the ignition coil and high-voltage wires; ignition coils cannot be repaired and must be replaced if faulty. 2. Fuel injection failure, possibly caused by wiring issues or poor fuel injection pressure. 3. Check cylinder pressure and the timing system. 4. Inspect the crankshaft position sensor. 5. Human operational errors, such as carelessness or mistakes during maintenance, leading to issues like loose connections or disturbed components. 6. Wear and aging, due to untimely maintenance or the use of substandard, unqualified, or non-compliant engine oil. 7. Engine malfunction, necessitating prompt replacement.
