Idle Air Bypass Valves for Ford Inline Six Throttle Body Installations
One of the most overlooked details when building a multi-throttle-body EFI system on the Ford inline six is the idle air bypass (IAC) circuit. On a conventional single-throttle-body or plenum-based EFI system, idle air control is handled by a single valve that bleeds air into the plenum independently of the main throttle butterfly. On a multi-throttle-body (ITB) setup — the kind used with Weber...
