Renault scenic 1.6 petrol, stalling intermitently.

[Albanais]

Hello to every body.

I have here a Renault scenic 2004, 1.6 petrol.
I am facing with this this problem: Vehicle intermitently stals, either you cant rev up more than 3000 rev/min.
The problem comes intermitently and randomly as well.
I am using renault clip for diagnosis, and the fault codes present on engine ecu are, 1 DF012 and 2 Df089. So until now I have checked : The battery is a brand new, the alternator is charging correct, I have fixed all the body earth points as well. They are changing from permanent in intermitetently, from red to orange. One other thing that I have noticed is that as soon as you start the engine, the vehicle losses the parking brake by its self, and on diagnosis is showing that clutch sensor is defective. Vehicles is equiped with a manual gearbox. I have checked as well the wiring loom and its connectors on engine compartiment , everthing looks properly mounted.
So has any one had any experience like this already?

Thank you to all of you in advance for any information given by you.

By the way happy new year.

Df089 - inlet manifold sensor
Df012 - sens supply no2 voltage

Exactly, the first code is df012 wich means ( the voltage on the accelerator pedal is incorrect on second field)

The second one is the inlet manifod sensor Or MAP.

I have already replaced those two sensors Accelerator pedal and the MAP sensor, I have checked the connectors and the wiring loom to each one of them, but the problem is still present.

Another fun, check pressure on gasoline.
And sensors on petrol rails, fuel filter, and the like.
There may be a problem with injection
