1st, vibration 12-1300 rpm to approximately 1800 rpm not in gear. My 2004 4.6 had the same problem. I now own a 2006 with a 5.4, still same problem. Unfortunately it appears to be a Triton engine concern, not limited to one version or the other. It does not bother me too much in gear and on the road. Is probably a design issue/vibration and most likely not repairable. All engines vibrate, some are designed to limit vibration in operation range. Many foreign manufactures use balance shafts to reduce or eliminate vibrations. American manufacturing does not and normally balance shafts. On a
V6 or V8, it is normally not a concern as the engine is balanced either internally or externally/ Not sure what Ford engineers did, but the Triton does vibrate as stated in many concerns listed here.
  
2nd, road vibration in 2004-? I had my 2004 in the shop for a intermittent vibration numerous times and the dealer I bought the truck from in TX could not fix it. Vibration on uphill climbs and light loading. In 05/06?, I happened to be headed to IL for holiday and stopped by the dealer in my hometown. 30 minutes later, never had the road vibration again. Dealer successfully balanced all tires ON the truck. Appears the 04 F150 extended cab maybe others are/is more sensitive to tire vibrations and amplifies the problem. Find a good tire or Ford dealer to balance the tires on the vehicle.
  
3rd, Engine miss at idle or on acceleration, I agree, have the plugs coils and wires checked and perform all routine maintenance. Remember the fuel filter, too many times it is left unattended too long and takes out fuel pumps or injectors. Run an approved injector cleaner through your tank once in a while, check manufactures recommendation. But using a good fuel that has cleaners to begin with is best in my opinion. If your favorite gas station does not post or brag about cleaners, they most likely do not have the best fuel in town. Use quality and manufacturer approved fuels.
  
Hope this helps someone!

Ford has that mentality about this on "The number one selling truck in the world." You would think they will have gotten their game together by now.
 
I would suggest using all available communication. Tweeting usually works! Facebook should get their attention. Remember, Facebook has the worlds attention. By putting a post on it will definitely get their attention. Facebook has over 5,000,000 people listening.
 
The truck looks good, the heart of the beast has a problem. There are only four parts they have to research: Engine (with over 5k miles); torque converter; transmission; drive-shaft. Each of the parts should be assessed separately. Then as a whole.
 
They should value their customer base, if they want us to remain loyal.

I will try this on my '95. The rotor on the front passenger side goes out at about 1,500 miles.
 
My Benz is having the same problem. I will start torquing only after the car is on all four wheels. It makes sense.

So i just bought a 1990 Ford F150 that had a few issues. 1st issue. Truck sometimes has a flux in idle but works itself out after a few min. CEL is on but nothing seems to be really wrong with it. ANY IDEAS. i would scan it but its not free here...Someone said to replace the TPS. Not sure if i should......2nd issue this thing shifts fine if you ease into the throttle. but if you stomp on it.... the tranny sound like it slamming into the motor..????? any help is helpfull.

I had the same issues as stated, our truck is an '08 /5.4L with 99,800 miles. I replaced the spark plugs, serpentine belt, Oil with Valvoline 5w20 synthentic along with z-max and prolong additives ( I do this every oil change). Then I removed and cleaned the throttle body thoroughly. After re assembly and rerun, the vibration and rattle disappeared after 50 miles or so. However, I cannot get the truck to idle below ~ 1200 RPM = to 45 MPH unless it downshifts to first gear which will then allow an idle of 700 ~ 750 rpm. Using too much brake to slow down. Anyone else have this problem? I have removed battery power to enable the PCM to 'relearn' the idle speed / fuel curve but so far no different result. Does anyone know of a good aftermarket programmer for this application? (Note I have a '98 with a 4.6L with 298,000 miles and never had any of these problems)

Hi, I was wondering, since the warranty company actually paid for your repair, may I ask which warranty company you have? Thank you

Don't know if you still have the truck or the question but the lifter noise is the cam phaser which retards the cam at low idle to conserve fuel and the engine vibration at varying rpms is most likely caused by this also. A slight tick is normal at idle a knock is not so if it is knocking or ticking abnoxiously loud buy the timing chain wedge and change out both cam phasers. If you try to do it without the wedge you will drop the chain and have to retime the motor.

I am having the exact same problems with my 1991 Ford F150 XLT 4.9L I6. Did you have any luck finding out what was causing both problems?

Yes, it is a characteristic of the truck. Ford designed that model to shake like that. I know because I bought one brand new. Long story short, it went to arbitration because it fell under the lemon law. Ford replaced everything on that truck. I met with the Ford field engineer who drove it then took me for a ride in a Lariat that did it too. He told me that it is a characteristic of these trucks and there is nothing they can do about it. He said Ford made the frame too stiff. What a bunch of BS. 6 months later I got all my money back, every penny and Ford took the truck back. Bought a Nissan. Love it.

I have a 07 Ford F150.. it does alot of vibrating when I slow down to stop. It shakes hard then quits on me. I have had it in a few times, they put it on a machine, the machine indicates nothing is wrong??? they just replaced cams today, thought that was the issue.. Ran the truck for awhile and it started again. Now I don't know what to do.... I was wondering if my intuition is right in thinking it has something to do with the Oil pressure?
 
When the truck is shaking, if I give press the accelerater it stops shaking???
 
ANY IDEAS??? please.. Thank you!
