I've got a '01 Supercrew Lariat w/5.4 and I have been having the same problem. Idles ok and when put a load on engine in overdrive it bucked. It ran like that for a couple months, sometimes it acted up and sometimes it didn't. Finally today it got worse, shuddering in any time the accelerator was pushed and the SES light came on. Well, I took it to my dealer and they told me it was a bad coil and 220 dollars later it runs just great now. Seems like a lot for one coil, I don't know. But seeing as how I'm not the most mechanically inclined I felt like I didn't have too many options.

My brother's F150 is having the same problem.
Does anyone ever post pics on this site?
If I could get a little more info I would gladly make a How To with full color pics.
Subscribed for later.

If you turn the truck upside down the vent tube on the tank will spill into the EVAP canister and it will need to be replaced because of saturation. To save the canister just remove it before flipping the truck.
All I can say is if you do this PLEASE take pics and post them on the site cause you will put this forum on the map with this method of replacing COPs.

cops
When these coils go bad you'll start to notice a miss at low rpms usually in overdrive at approx. 45-50 mph. It will be random, then gradually get worse until it completely fails. I'd say on average your fist one will go at around 100k miles. These things are like $25 bucks at an auto parts store. You mine as well buy all 8 and new plugs. Spend $220 bucks and be done with it so you don't have to worry about it again. If you have an air gun blow out the hole where the spark plug sits so when you pull the plug no crap gets into the engine. Put a bunch of dielectric grease around the boot when you put the cop on. The ave. Joe can change all 8 in an hour. The passenger side should take you 20 minutes and you may spend 40 on the drivers, but they will come out with no problem and you don't have to pull the fuel rail. Just be careful when you disconnect the wire going to the cop, that you don't break the little tit that holds the connector onto the cop. If you do then you'll have to rig up something with wire ties to hold the connector on. Also beware to tighten the plugs close to the torque specs. If your an engineer $220 bucks(which would be about what you make in a few hours at work) for basically a tune up isn't a bad investment for one of the very few common problems on these trucks. And no you don't have to spin the engine to change the cops hahaha
