I went 5 times to my dealer, but there are no problems detected.
But when I go the car is worm and it's OK. I have to leave the car in the
service for a day and connect it to the diagnostic tool when it's cold.

And what?
The ECU sends maximum of fuel, because it doesn' t know the
gass pedal position. So the lambda sensor determines the fuel
mixture? And you don't need a throttle potentiometer for $300?

No,
The engine is perfect. The oil level doesn't change in 10 000km period.

And for throttle potentiometer. I think that the engine can't work
without this sensor The fuel mixture depends on it
This ECU is not a super computer

I tried to disconnect the lambda, but the result was the same.
And my lamp didn't flash. I think the lamp is disconnected by
the seller

My oil and water are stable. There are no leaks and level changes.

I know that the lambda is old and it's lazy. But works.

You mean a throttle position sensor (potentiometer)? I think it is OK, because it is renewed before an year. (about $300 ) But is it the right voltage on idle? Now the voltage is 0.7V. The person who made the settings didn't know the right values. In the Autodata program the idle voltage is 1V. What...

I thought that the problem is in the temperature sensor, but I did some tests with constant resistors and the situation was the same. I noticed the good activity of the stepper motor, so it works. When it's cold and I start the engine it works at low idle speed. After 10 minutes the idle speed rises...

I have:
AX 1.1
Year: 92
Monopoint injection
Bosch ECU, but I don't know the version

Thanks for your answer!
Is it the right place for this?

Hi all,
I have a problem starting with cold engine. When I start the engine
I have to wait about 5-10minutes. In other case it doesn't work
steady and the mixture is very rich.There is a black smoke.
