Hesitation acceleration

Hi,

First, this vehicle isn't offered in the US, so my technical information is very limited. However, I will try my best to help.

Since you notice a power loss on hills, the first thing I would recommend is to confirm fuel pressure is within spec. When climbing a hill, the engine is under more of a load and requires more fuel, so if the fuel pressure is weak, it can cause this.

Here is a link that explains in general how it is done:

Let me know if this helps and what you find. Also, if you have other questions, let me know.

Take care,
Joe
