Hello to all who can read this post and maybe help me ;o) Escort Combi with automatic BJ 97 1,6l 90PS I was at the TÜV and who said…Unfortunately not passed because the last measurement ( Lambda Start not available) could not be made, as the speeds varied between 700 and 850. The good TÜV (B) angel said the engine ran very thin. Possible cause: False air vacuum box spark plugs Lambda probe If still missing information (except Kontornr and Pin) please report ;o) For help I would be grateful and give out a bottle of Maggi ;o) Many greetings to all
