wires unless abused
i.e. yanked on tend to stay good for a long time,did you remove all the coils?or just one?usually if you suspect one coil is bad you can just swap it to another cylinder and see if the problem follows the coil.
Do you have any misfire codes?What cylinder?
shaking that hard you should have a cel on and the code would show what cylinder or cylinders were misfiring.
Have you check you motor mounts?

The motor mounts are new (both). Both coils are out. With that much shaking surprise there is no CEL.
With all 4 spark plug wire & 2 coils all out, how do i test them without the need to put back the air intake manifold, throttle actuator, engine wire harness etc back together again.
