Beware of a very high depression level behind the throttle.
At high RPM it can reach 100mbars (1.4psi).

I'm in France. Where the engine is from ... I don't know,
it's just lying down in a yard.

I think it's relatively modern, less than 10years old. I would
say there is an air injection in the exhaust (with an air pump),
but I'm not sure as hoses are broken.
There are 2 coils for 4 cylinders, they are mounted under a red
alu cache screewed on the top of the head.
Injectors are mounted on the intake ports, not on the head.

Neither me :-)

No, it's a pure Bosch part.

Thank you,
