Top off coolant system and re-test

you have a leak in the vaccum line to the hvac system

Notorious for intake leaks, the composite plastic intakes crack and leak coolant-as to the lack of power, you mght have overheated it and done some damage to the engine. There was a recall (information below) for the 4.6 for the intake-the overheating and lack of power means you should at least have compression checked and go from there-you may have bad head gaskets or worse. Do a compression test before you do anything else.

Ford Motor Company will extend the recall (01M02) on 4.6L V8 equipped vehicles with plastic intake manifolds. Some of the composite intake manifolds used on 4.6L SOHC engines may develop fatigue cracks at the coolant crossover duct. This condition could result in engine coolant leakage which, if not serviced, may cause engine overheating. Complete loss of coolant may result in engine damage or engine failure.
The updated recall now includes:
• Certain 1996 through 2001 Model Year Crown Victoria Police Interceptor
• Certain 1998 through 2001 Model Year Crown Victoria with Taxi
• Certain 1998 through 2001 Lincoln Town Car Limousine and Livery Prep Package
• Certain 1996-2001 Crown Victoria Taxis, Police cars and Lincoln Town Car Limousine and Livery cars.
• Certain 1996 through 1997 Crown Victoria Police Interceptor Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from the beginning of production for the 1996 Model Year through January 28, 1997.
• Certain 1998 through 2001 Crown Victoria Police Interceptor Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from November 22, 1997 through December 15, 2000.
• Certain 1998 through 2001 Crown Victoria Taxi Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from November 22, 1997 through December 15, 2000.
• Certain 1998 through 2001 Lincoln Town Car Limousine Prep Package and Livery Vehicles with 4.6L SOHC engines built at the Wixom Assembly Plant from November 22, 1997 through December 15, 2000.
