you do not say if your engine is gas or diesel. A gas engine has many sensors, any one of which could cause a problem, not to mention a borken catalitic converter, which could also have many causes.
I have not found any reasons for a diesel to experience this problem.
I think, that to correctly answer this question, you need to give a more detailed question.
A plugged fuel filter, A plugged catalytic converter,
Your piston rings are probably bad. Which will cause compression loss, in effect you will loss power, and it will let oil trough and saturate your plugs.
Re-build your diesel. Put on a custom chip and that will make up for engine power loss.
If the check engine light is on then have it scanned for codes. I could guess you into bankruptsy. It is cheaper to have it scanned and repaired.
What does reduce engine power means?
Yes
Power engine loss refers to the reduction in the engine's ability to produce power, which can result from various factors such as mechanical wear, fuel inefficiency, or issues with the air intake or exhaust systems. This loss can lead to decreased vehicle performance, including slower acceleration and reduced overall efficiency. It is often measured in terms of horsepower or torque and can be influenced by maintenance practices and engine modifications. Understanding and addressing power engine loss is crucial for optimal vehicle operation.
* No power steering fluid in reservoir * The power steering pump is not operating
Loss of power, white smoke out the tail pipe, and under extreme cases engine knock. By then it's probably too late.
It sounds like a power loss......... tune-up, get tranny checked out
Oil leakage and loss of compression and power loss.
A loss of power in a C180 when the heating is on can be attributed to increased electrical load on the engine's alternator. When the heating system operates, it draws additional power, which may strain the engine, especially if it's already under load. This can result in reduced engine performance and responsiveness. Additionally, if the battery or charging system is weak, it may exacerbate the issue, leading to noticeable power loss.
