Aveo Diesel - Error Code 89

[hjaem]

I have now chanced the lambda. Then erased the code. And after 200 meter it occurs again. But it was when I accelerate on fourth gear at 3000 rpm, just before I shift to the fifth speed. Maybe to hard for the car. I erased the code again and drive not that hard, about 400 km whiteout an error message.
I have to drive more before I really know if or how it works.

I have also think about if a spark plug could case the problem. But I haven´t chanced some.
But earlier in this thread someone got the hole engine chanced and error 89 still occur! So maybe not...

Good question about the fuel consumption. It´s around 4,6 lit/100 km in my car.
It was around 5,5-5,8 the days before I chanced the lambda but now 4,6 again.
So little lower than yours. I don´t know what it means...

Last 5 days the error came back 3 times and all in the same situation.
Driving on the highway, normal speed around 120 / 130km.
When the error pops up, I felt some kind of power loss. I tried to drive harder, pulled down the gas, but the car had no traction.
This all happened less than a minute and the traction and power was back again.
Maybe, like I said before, malfunction of a sparkplug or something
When I erased the code everything was fine again, till the next pop up...

Keep you informed,
