2010 F150 V8 5.4 Triton Engine Problems
 

First time to post on the forum but I'm desperate to find an answer as I have taken it to my local mechanic and he cant figure it out.


Truck normally runs fine but if I go slow and hit bumps in the road or drive through a field the engine starts shaking and it sound horrible but if I rev up the engine it goes away. Not sure what it is but need help on what to do to fix the problem. Any suggestions would be great on what steps to take to fix the problem? Thanks
