So I started a thread here: http://www.stangnet.com/mustang-for...-maf-and-iac-valve.873766/page-2#post-8783468 General advice was that I should get a tester and pull the codes. Tester came in today and I performed the koeo test. It gave me codes 31, 81, and 82. It froze here for about 5 minutes and never put out the separator code or the cmm codes. In addition when I performed the koer test it did nothing until the tester eventually turned off. My mods are listed as they were told to me in the picture.
