Am I looking at getting a new set of injectors or should I try and SeaFoam it first ? The engine is 4.6 with 94,000 on the clock and has been serviced religiously by it's previous owner ....... it was his late wife's car and has sat parked since she past away about 4 years ago .

Check every COP for rust. I had this same symptom on my '96 Cartier and it turned out to be a rusted Plug Wire.
