What are the causes of multi-cylinder misfire in Honda 1.8 engine?
1 Answers
Multi-cylinder misfire is caused by poor spark plug contact, excessively high injector voltage, non-functional ignition coil, or insufficient cylinder pressure. Causes of multi-cylinder misfire: Poor spark plug contact may lead to momentary ignition failure, resulting in cylinder misfire. Excessive self-induced voltage in fuel injectors can cause sticking in the next working cycle. Poor heat dissipation of the internal transistor in the ECU may lead to ignition coil failure. Insufficient cylinder pressure can cause ignition failure. Key points of engine maintenance: Use appropriate grade of engine oil, regularly change oil, oil filter and air filter, periodically clean the fuel system and replace spark plugs.
