When to act urgently
Stop if power loss is sudden, warning lights flash, or the engine overheats.
Common possible causes
- Ignition or fuelling problem
- Restricted airflow or exhaust
- Sensor fault
- Clutch slip
What you can safely check
- Note the speed and engine conditions
- Check for warning lights
- Avoid forcing the car under heavy load
What not to attempt
Avoid dismantling safety-critical, pressurised, hot or high-voltage systems without suitable training and equipment. Generic symptoms are not enough to choose a repair.
How a workshop diagnoses it
A technician will confirm the symptom, review relevant vehicle information and use physical, electronic or measured tests as appropriate. The aim is to separate the underlying cause from related symptoms.
