The truck is a 2001 f150 it stumbles after I speed up on highway going at a steady pace, it jerks , but when I press gas pedal to speed up it stops as soon as I reach my speed I softly ease off pedal n it begins to jerk or stumble..

Ok. I just wanted you to come to this point and learn it's important to be accurate before I said the following..
.
NOW, you have a 99% chance it is one bad coil.
To find out which one, use a Scanner to look at mode 6, test 53 (as Ford calls it).
This is the 8 individual cylinder misfire monitors.
The one/s with the counts out of limits is/are your trouble.
Replace the coil.
Good luck.

What coil did you ID as a fault?
The faulty coil for this type of drivability normally sets no code.
It has to be found by looking at the misfire monitors.
There is a explanation behind why it sets no code.
Good luck.
