Ford Expedition True expeditions require additional transportation conveyances: horses, boats, cars, for example. With a towing capacity around 9,000 pounds, the Ford Expedition can tow any of these. Ford adds a new top end King Ranch model for 2008, as well as an available rear backup camera and power-retractable running boards. The Expedition is meant for utility, not posing.

If you have a Modis, then you know better than to trust those coils... what misfire codes are stored?

Default modis

I wish it was mine but I have to check it out -toolroom.
Your right the modis did tell me good specs which left me guessing. What I did find was that on my 98 (4x4 xlt) Was that the heater core hose was (the one with out the wrap) resting on a conector to the coil. I re-arranged it with a zip tie so that there is no contact.
Today it was about 92f. So far no worries.....
If it happens again then I'll check the coils with a dmm.
