Hello to everybody.
I own a AX 1.4 92model year with KDY A2.2 Bosch engine.
The last days when i start the engine the idle speed gets to 1600-1800
rpm.After 5 min of driving and the engine gets hot the idle speed
falls to 1200-1400 rpm.
In every occasion the idle speed is stabilized and has not ups and
downs.
I have not any trouble codes.
I am between the coolant sensor and the stepper motor as defective parts
but i don't know which one...
Any advice how to check those parts or others parametrs would be
appreciated.
For better conclusions this engine does not have lamba sensor.
Thanks in advance
Vaggos
Just change the coolant sensor,
the stepper motor costs about 20 times as much...

I have already change the coolant sensor but still the same problem....
Another aspect might be the throttle pontensiometer....
But still don't have any error code..
