Black smoke from the exhaust when going uphill typically indicates incomplete combustion of fuel, often caused by an over-rich air-fuel mixture. This can result from issues such as a malfunctioning fuel injector, a clogged air filter, or problems with the engine's sensors that regulate fuel delivery. Additionally, increased load and reduced airflow while climbing can exacerbate this condition, leading to more soot being expelled. Regular maintenance and diagnostics are essential to resolve these issues.
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
