It's a kangaroo jerking back and forth in the 3000-5000 range only when I apply full gas if I press the gas pedal very slightly now and again this may not happen but if it does it won't be as violent as full throttle!

Hi there good evening to you
Ok The first check that should be done when we see this type of fault is the IMRC (Intake Manifold Runner Control
What we tend to see is low torque/power or hesitations between 3000 - 5000 rpm this can most commonly log DTC's P1518 / P1519 inthe PCM ( powertrain control module
the most common cause is a broken lever which connects the intake manifold and the intake manifold runner control (IMRC). Due to the broken lever the variable internal runners are without function.
When you start the engine up the IMRC on the side of the inlet manifold should be drawn forward by means of the IMRC control cable connection
If this lever is broken it can cause such an issue
If this is the case Then to rectify this concern it is not necessary to install a new intake manifold. A revised lever kit is avaiable and should be installed.
The ford part number of the revised kit is -(###) ###-####
If you need anymore help or advice on this issue please let me know
If you are Completely satisfied with my answer /advice
PLEASE RATE MY ANSWER
Kind regards ***** ***** and have a nice evening
Any positive feedback /bonuses are greatly appreciated
