I just bought a 04 Excursion 2 months ago and I have started having a promblem with the truck not responding when I push the acc petal down but truck still idles and I have to turn it off then restart it for it to work again but I dont know where to start to fix it. Now it idles rough when I stop at a stop light or even breaking to slow down then dies. I can normal get it restart but I have had it start and bearly run like less then 500 rpms. I need help. I plan on changeing the fuel fitters and cleaning the EGR but really dont know if that is going to work.
