Misfires at low RPM can be caused by several issues. Faulty spark plugs or ignition coils are common culprits, as they may fail to ignite the air-fuel mixture properly. Vacuum leaks can disrupt the air-fuel mixture, leading to incomplete combustion. Additionally, a clogged fuel injector might not deliver enough fuel to the combustion chamber. Regular maintenance can prevent these issues. Start by checking and replacing any faulty components and ensure the vehicle's systems are clean and properly tuned for optimal performance.
FAQs & Answers
- What are common causes of engine misfires? Common causes of engine misfires include faulty spark plugs, ignition coils, vacuum leaks, and clogged fuel injectors. Each can disrupt the air-fuel mixture or hinder combustion.
