Resrictor in throttle body. - 3/21/2006 4:19:51 PM    tagbartok   Posts: 1 Joined: 3/21/2006 Status: offline Hello During a general tinkering session over the weekend I removed the throttle body from my 1991 Audi 90 2.3 20Valve (7A engine) to give it a thorough clean. When it was off I noticed that the butterfly valve plate in the primary choke has a shaped wedge of alloy screwed to it. It would appear that it acts as an airflow restrictor. If this is what it's for why is it fitted? Why shouldn't I remove it? Does anyone know what it's there for and why Audi fitted it? Thanks, Tag[/size] _____________________________ Audi 90 20Valve Post #: 1
