1994 F-150 Driver

Well I feel like a dumb a** but that's okay. In my attempt to get my EGR off to clean I loosened the top bolt a week ago. Well the bottom one didn't budge so I didn't take it off, leaving the top bolt loose. Tightened it back down and it purrs like a kitten now. Officially fixed. Thanks to everyone for helping and putting up with some of my stupid questions. This forum is great.
