Moin, 95er 2.0 16 v suffers from more or less violent jerking after the end of the cold start phase. This error only occurs since the Lambda probe wg AU changed to Tüv (sigh). Initially, errors 038,039 and 19 came when using a Unifit probe.After switching to original part Opel at least the error indicator was gone.Unfortunately, it still jerks away. Mistakes are still not filed.MKL is out – nothing in the memory. Just for the sake of caution LLR and the Paintedeite hollow screw cleaned but has only a lower idle speed causes about 900 rpm instead of 1100 rpm. Where are possible sources of error? Greeting RolloX
