Anyone in the Maryland area had their butterfly valve screws checked? If so, did you do it yourself or where did you have it done? I have read all the threads on the site, but I haven't seen one where someone has mentioned where. I was thinking of going to altered atmosphere to get it done, but if anyone out there has a suggestion let me know. My car is a '03 with a 10/02 build date, and I am just under 17000 miles. Thanks for the help
