Hello, I have a 2004 Renault Scenic with 270,000 km and I notice that black smoke is coming out of the exhaust during acceleration. What could be causing this problem and how can I fix it? Are there any specific points I need to check or watch out for?

Black smoke during acceleration often indicates an overly rich fuel mixture. Start by checking the air filter to ensure it's clean and not clogged, as a dirty air filter can restrict airflow and cause this issue. If the air filter is fine, consider inspecting the fuel injectors for any signs of clogging or malfunction. Let me know how it goes or if you have any further questions!
