I have a 2002 explorer with the 4.0. It lost most power to where I couldn't drive it . I got codes for the egr valve . I replaced that along with the pressure sensor. Now it wont start at all .it will fire if I hold the accelerator to the floor , but only fires for about a half of second. Any suggestions?
