1. Google death wobble and you'll see what death wobble is. Short explanation= the whole front of your truck bounces like an overinflated basketball.
2. The more informed will need more info on your truck/engine to give adequate advice on your engine woes.

Hmmm...put one of your old coil on the cylinder that is misfiring and see if that helps. If so, then that coil is bad.

I'm not sur on the V-10 but the 5.4's will throw bank lean all the time with a dirty MAF! It sits right up by the air filte and seems to get loaded up pretty good!
Death wobble is most common on coil sprung trucks BUT! Can and does happen to leaf spring front ends as well!

Have the steering wheel dipped out of your hands at 55mph with a 18k lb 39' fifth wheel behind you as it shakes the truck ^so bad you can hardly see the wheel to re-grab it....and you'll know why it's called "death wobble"! One of the most effective bandaids for it is a steering stabilizer, but usually the panhard rod bushings are worn, along with insufficient caster, and bad ball joints & tie rod ends are the combination of worn parts that make it very susceptible to death wobble!

Wondering if you used genuine Motorcraft replacement spark plugs when you replaced the plugs? I have read of cases before on this forum where off brand plugs sometimes caused misfire problems. Seems these motors can sometimes be touchy that way.

I'm doing plugs for the first time in both my '98 & '99 5.4 expeditions this weekend, they have never been changed 191k on the '99 & 149k on the '98 what brand is best! Any recommendations, gaps have been ok at factory spec? Or has anyone tried a different setting with success for very high mileage motors? I'm a little nervous of stripping them out! That's why I haven't changed them, but I'm seeing a downward trend in mileage and performance, ^so I'm sure it's time!
