It depends on the motor im not sure if the eldorado ever came with a 4.9 but I know on my eldorado it was underneath the intake manifold...which involves taking the fuelrail off and is not something I would recommend doing by yourself if your not a mechanic but if you do make sure you change the injector o rings because leaking after this is common and can lead to a bad motor fire.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
