That might be a problem with motor mounts. Raise the hood,start truck and while holding the brake put in gear and slowly press accelerator. A bad motor mount will allow the engine to twist in place. Don't forget to check the transmission mounts also.

Hi, my car starts vibrating at 2800 RPM and vibrations dissapears at 3000 RPM.


does it have the same acceleration at that speed, if it does not accelerate so well it is called a flat spot and will almost certainly need a good mechanic to sort it out
If acceleration remains as good in this range as through the rest of the rev ange add detail and please resubmit

Vibrations


sounds like a misfire, if it is 1996 or newer have somewhere like autozone scan the computer for you and see if there is any codes for a misfire, if its older than 1996 then i personally would start it up in park, then pull off spark plug wires one at a time (use pliers and gloves, dont get shocked) and then plug them back in. see which ones change how the engine sounds and how much it shakes or stalls.

if one makes a big difference in how it sounds then that one is firing, if it makes little difference then it might not be firing properly, could need a new plug or wire.

Idels fine in park but in gear runs rough


By "runs rough" if you mean vibrations then check your motor mounts. One or more could be broken.

05 f150 5.4 vibrates when ideling in drive oe reverse but not when in park. even in the brake pedal you can feel it


Visually check all Engine and Transmission Mounts. Check for loose and/or broken bolts. Next individually check the rubber mounts each for cracks or tears. It might be advisable to support the engine, loosen and remove the mounts, inorder to check them thoroughly. When you shift into gear (drive or reverse) this causes the Engine to physically shift also. If the mount is bad then the metal rod holding on the rubber mount goes makes contact with metal causing vibrations.
Let me know if this helped, or if you have any additional information, questions or problems. Feel free to contact me at FixYa.com!

Vibration after 50 mph, and when accelerateing after 50 mph, worse when you accelerate, very little when coasting. but only after 50 mph


Welcome to fixya the best thing to do is check the rims for imperfections and slight bents that causes the vibrations at that speed go to www.collisionrepairadvice.com to get a wheel repair company to look at.

Vibrations, tranny slipping, and engine tick


Sounds like you may have a worn out CV joint and the clicking may stop with an oil change. Good Luck
