I have a 2004 f-150 with the 4.6 motor. It has been in the shop numerious times for engine problems. Three times for fuel related problems where it runs out when it is not empty. One time both heads were replaced. A month later started running like crap again and ford said that one of the spark pluds gap was closed completely. Now how could that happen. Now another month later it has failed again. This time they say one of the cylindars has lost compression again and they are going to replace the heads again. I am not a mechanic but I do know that this is not something that should be happening to a truck with 30,000 miles on it. Anyone else having problems like this.

 

no,but i'd get them to give you a new truck after all of your lemon problems and up for the 5.4.
