I would really like to talk to you. I leased a 2008 Ford F-150 FX4 in January. I have 10k miles on it and it has been at the dealership a combined total of 19 days and is currently there right now. I have a vibration while driving at highway speeds since I bought the truck. They have rotated and balanced the tires numerous times. Does not fix the problem. My service guy told me that a FORD Engineer was coming to look at it this week. You can contact me by email at chadprocessingpros.net My cell number is 702-334-4008. I live in Las Vegas.
 
I even had a guy at a gas staion walk up to me and asked me if I liked my truck. I told him about the vibrations and he is having the same problem at THE SAME dealership.
 
Look forward to hearing from you. Chad

#107 of 182 Rough idle between 60 and 100 km/h by macisaas

I own a 2001 F250 and notice that this seems to be a common problem occuring in all F-series trucks, has anyone got any ideas what could cause the rough idle, in my case this is intermittent and when I mash on it it goes away then returns when maintaining a constant speed. I have changed my fuel filter as well and was told that if the coils had and issue there would be a code. All suggestions are appreciated.

I had the same problem on my 01 F250 V10.
 
Don't believe the techs when they tell you bad coils will throw a code. They will ONLY if they have continuous misfires.
 
Intermittent misfires won't throw a code. If you have anywhere near 100k miles on the truck, you need new plugs AND coils.
Do a search on ebay, you can find them for around $100 for a full set, vs $45 each at the dealer. Get Autolite plugs at the local parts store.
 
Changing the plugs/coils yourself will require patience and about 2.5 hours. Use dielectric grease on the boots.

Thanks, that was going to be my next attempt at fixing the problem, I will definately check e-bay for the set I really didn't want to spend the money on them all at the dealer. I aprreciate the rapid reply.
 
Cheers.

I have a 2005 Ford F-350 King Ranch. On my way to work this morning I experienced a violent vibration when my front tires hit a bump on the freeway; i was going 65-68 mph when it happens. It scared the hell out of me, my truck is stock not lifted. May be we should start a petition regarding this problem with Ford F-250, 350, 450 truck series. Let me know.

Dodge Ram owners know this as "Death Wobble". You need to check the following to resolve it:
- tire balance
- a worn shock
- ball joints
- remaining front end components
 
You will find one of those will be out of spec.

we too have a new F150 STX bought in August 08. Since then it has been in the shop for almost a month. It has had 14 new tires of different brands, new rotors, new drive shaft, and no difference. The Ford engineer said it was not fixable to our service manager. Then he told the Division person it was in an "acceptable" range. How is it acceptable when at high speeds it shakes enough to mix a drink and when you go over a rough spot the front end feels light and out of control.
We also drove 3 more F-150 2008 an 2009 and they were worse than ours.
Ford now will not do any more to fix the problem.
Have you thought anymore about a class action suit? Our Service manager said he will support us with documentation.

Did replacing the coils and plugs fix your problem?
 
I have an '04 F150 4.6L with almost 70K miles that has a rough idle while sitting still, and has intermittent (though frequent) misses while lightly accelerating and then after I have leveled off to maintain a constant speed.
 
It is getting a little worse each day.
 
I had it hooked up to a diagnostic machine at a local auto parts store that read a misfire on cyclinder 2.
 
I had the fuel system professionally cleaned, air filter changed, oil changed, and it still is doing it.
 
I was just wondering if you got your problem fixed because it sounds the same as mine.
 
Thanks!

I haven't quite got to that yet, I am going to try another fix, I was told it could be the torque convertor clutch and I have disconnected my battery to reset the computer and it seemed to run fine the first time out, but went back to it's old trick on the second run so I am going to try it with the overdrive off and see if it still does it, if not it is likely tranny related if it still does I will be doing coils and plugs. I will post as soon as I have a fix for my problem.
