Ford F-150 1992 stalling at low idle with extremely hot exhaust and oil in airbox on Ford F-150

Some 1992 Ford F-150 owners report experiencing stalling at low idle, which may be linked to rough idling caused by issues with the fuel system, ignition system, or air intake. A common cause of this stalling is a faulty Idle Air Control (IAC) valve, which can disrupt the air entering the engine and negatively impact performance. Additionally, some owners have noted that a malfunctioning fuel system, such as a clogged fuel filter or damaged fuel line, can lead to insufficient fuel delivery, resulting in stalling. Furthermore, excessive oil consumption due to a bad PCV valve has been reported, which can cause oil leaks and indicate problems with engine oil management. To address these issues, it is advised to check the IAC valve, inspect the fuel system for clogs or damage, and evaluate the PCV valve for leaks.
