Members I have a problem with my 1998 Eddie Bauer 4x4 5.4L Expedition. When cold and even sometimes when warm while drivering the expedition starts to shudder and hesitate at 45mph and continues on up. I have changed the COP's, plugs, fuel filter, transmission fluid and filter. At times the engine light will flicker wile the shuddering is happening. No codes will display. My EXP has 176000 miles. It idles fine and for the most part runs fine except for the issue noted. What could cause this current issue?
Last night I drove the truck with the Overdrive off. No shuddering at 45 mph. Could this issue be related to my transmission?
