no power climbing hills · engine bogs down under load
The engine feels noticeably weaker and struggles to maintain speed when climbing a hill, towing, or accelerating hard, compared to flat, light-load driving.
Check the air filter condition first - it is the cheapest, most common cause of a general power loss under load.
Usually safe to drive, but avoid situations demanding sustained high power (steep hills, towing) until it is diagnosed.
Describe your situation more precisely (e.g. exactly when it gets worse, how long it lasts) and get an expanded, personalized breakdown.
