ISSUE:
Hard starting at normal engine operating temperature after a 15 to 60 minute hot soak may be caused by fuel vapor getting to the engine
through the fuel bowl and evaporative emissions system. The fuel vapor will cause an over-rich engine during restart. Volatility of gasoline
may also cause increased amounts of vapor when gasoline is warm. The affected vehicles are 1984-87 E and F Series with a 5.8L engine and
Holley 4V carburetor and 1983-87 E and F Series with a 7.5L engine and Holley 4V carburetor.
ACTION:
To correct this, install a Hot Idle Compensator (HIC) valve using the following service procedure.
