Black smoke on acceleration on my Toyota Corolla petrol

Hello everyone, I own a 2019 Toyota Corolla with a gasoline engine and 120,000 km on the odometer. For the past week, I've noticed black smoke coming from the exhaust when accelerating. Could you help me understand where this problem might be coming from? Should I be worried? Thanks in advance for your advice.

A 2019 Toyota Corolla is emitting black smoke during acceleration, indicating a potential issue with a rich fuel mixture. Possible causes include a clogged air filter or malfunctioning fuel injectors. Suggested solutions involve checking and possibly replacing the air filter and inspecting the fuel injectors for leaks or malfunctions.

Black smoke from the exhaust usually indicates a rich fuel mixture. Start by checking the air filter to ensure it's not clogged, as this can restrict airflow and cause the engine to run rich. If the air filter is clean, it might be worth inspecting the fuel injectors for any leaks or malfunctions. Let me know how it goes or if you have any further questions!
