No idle when cold after changing lambda

[Jonahhex]

Good afternoon!

I have solved a problem and ended up with another. One of the lambdas was broken. I changed it and now the car wont idle when it is cold. After a minute or so it is fine but not I have to give it a little throttle just to keep it at around 1000rpm or so until it gets warmer. Any ideas?

Did you reset the adaptives after swapping it?

I didnt do it myself so i am not sure. What is that and how is it done? Next time i will do the forum before i start...

You need the diagnostic lead and software, I presume the company that diagnosed the bad lambda had it ?

What was the cold idle rpm before the replacement lambda?

Hi,

I am not sure but around 800?

I will get this fixed for next summer. This winter I will focus on all other electrical failures...

I havnt got the equipment to fix it myself so I will just have to wait.

Thanks!
