Electronic butterfly failure

Hello everyone: common failure in many gasoline engines provided with electronic control of the acceleration butterfly, especially of first generation. (The first)

Symptoms: irregular slowdown.
The engine is covered or off especially in deceleration faces (reaching a semaphore)
the RPM drops more than normal being the engine at idle when applying a load such as the air -consistent air, hydraulic direction, important electrical consumer, etc.
In addition, if you look at the acceleration body with the engine at idle, you can realize that the butterfly controlled by the engine control module, is moving quickly and consecutively, more than normal.
Generally these BAN symptoms increase gradually until they begin to turn off and the cars do everything described above.

How to identify an electronic butterfly engine? Simply because of the exaggeration of mechanical connection between the accelerator pedal and the butterfly body (it has no cable or accelerator piola.


Additionally
and very important, after verify The
Acceleration Corps, especially in the allocation of the gase butterfly .

does not damage the varnish that all electronic circuits have

etc. Most of the first generation Drive By Wire systems, because in the most modern and/or expensive the engine control unit has sufficient processing capacity for detector a problem like the one described and can generate varied fault codes (DTC) to the respect (Chech Engine on), helping a lot in the speed of the diagnosis . Raize learning process of the new operating conditions of the butterfly cup electronically controlled by the engine control unit.
