2000 Mercury Mountaineer P1507 Fault: Idle Air Control Valve Issue at Low Speeds
My 2000 Mercury Mountaineer is showing fault code P1507 and the engine idles too low, causing it to stall intermittently. Does anyone know how to diagnose or fix this issue? Any advice would be greatly appreciated.
Check the voltage supply to the Idle Air Control (IAC) valve. If power is present, begin by cleaning the IAC valve with a suitable cleaner. If the problem persists after cleaning, the IAC may need replacement.
