Two problems related to gasoline fuel system have been reported for the 1999 Ford Expedition. The most recently reported issues are listed below.
I have a 1999 Ford Expedition XLT with a 5. 4 l v8 with 130k miles on it. I started my vehicle this morning and it sounded like the engine had exploded followed by grey smoke coming from under the hood. After inspecting the vehicle I discovered that the passenger side , second from the rear spark plug was blown out of the cylinder head. After some research I found that this is an all to common problem for certain year model Fords. This a very dangerous defect and not only could someone get injured or stranded but could also be lethal if the gas from the cylinder were to ignite under the hood causing an explosion or engine fire. Something should be done to prevent this.
SUV stalled fuel vapors filled inside SUV smoke then filled inside,we got out lifted hood a fire was starting on driver side near wall, my son and I stood back fire was dropping from the engine we got away from the vehicle it exploded 3 x. I received lung life long lung damage, the incident had never occurred before,the vehicle was not salvageable.
