Your 1999 Ford F-150 may be running rich due to several potential issues, such as a malfunctioning fuel injector, a faulty mass air flow (MAF) sensor, or a clogged air filter that restricts airflow. Additionally, problems with the engine's oxygen sensors can lead to incorrect fuel mixture adjustments. A leaking fuel pressure regulator could also cause excessive fuel delivery. It's advisable to conduct a diagnostic check to pinpoint the exact cause.
