Low speed vibration
99 F150 has a tremble or vibration between 27 and 40 MPH it does it in any gear but only between these speeds. I thought to begin with it might be a slight misfire, but seems like if that was the cause it would happen at any speed/ Any ideas?
Thanks
Bobby

Nothing yet it's my sons truck and he told me about the problem yesterday. I drove it today and that is what I found. No noise that I can hear just a tremble or vibration between 27 - 40 MPH. As I mentioned I thought it could be a misfire from a faulty plug or wire but not sure. I put it in low and took it to 30 MPH and it was still vibrating but it stops after 40 MPH.

Do a coast down in gear and out of gear through the same speed range to see what happens.
You have to begin looking for a specific set of conditions.
We just cannot guess the issue until you get some kind of lead.
Good luck.
