I have a major problem and my mechanic is out any ideas
First we changed the EGR ventil but this didn’t help, after that he changed the first lamda sonda and the idle stepper motor with no success. I then called a second mechanic and told him all the problems and changes we have done, and he says that the problem was in the body throttle. The worst thing i cannot order anywhere a new part so i ordered a used part with guaranty. The part came he installed it but wit same problems the Car starts and after some time its just turns off.
Any suggestion what to look further, my Car is a Xsara Picasso 1.8 16V 2001
Thanks in advance
