So I ve exhausted all the ideas I had on fixing my expedition, not only can I not drive the Heep, but now cant keep the tow rig running, anyone have a good mechanic theyd like to pimp or someone on board a mechanic and good with fuel injected super charged ford engines? Im really in a bind without this thing and getting more and more pissed as the day goes on. Its sputtering at any rpm, kinda like a misfire or lack of fuel, trouble shooting already done: fuel filter, and plugs, niether helped.
