I was running the open track event at the Mid-America Shelby Meet in Tulsa, OK, and having a great time. All of a sudden, I came into the pits after a session and the car wouldn’t idle at all; it would die once you let off the throttle. We jumped on the problem immediately, even rebuilding the Holley at the track, but to no avail. I ended up towing the car home, fearing that I’d really done something terrible to it. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Once I got it home and started looking closely at it, I discovered that the brake booster vacuum line had slipped off the nipple on the intake.
