Question about 1995 Mercedes-Benz SL-Class
I have a 1991 sl 500 engine runs rough at idle and when sometimes when driving when take foot of the gas it stalls out it just passed emissions so can i rule out o2 sensor and could it be fuel pressure regulator
Sounds like your Idle Air Control Valve is starting to go bad. Normally I just tell people to replace it because it's a cheap easy fix, but with your particular vehicle it costs over $400. With that in mind, I would recommend either replacing it or trying to clean it with some throttle body cleaner. It is located on the throttle body and here is a link to AutoZone to give you an idea of what you are looking for:http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?categoryDisplayName=Engine+Management&fromType=parts&fromString=search&parentId=cat30067¤tPage=1&filterByKeyWord=iac&isSearchByPartNumber=false&navValue=15900207&categoryNValue=15999999&fromWhere=&itemId=prod61721&displayName=Idle+Air+Control+Valve&searchText=iac Good luck and thanks for using FixYa!
