**** Plugs misfiring. This happens under load only. Had very same problem
with my 4k. Started and idled fine, but would "buck" under load.
The solution was new plug wires.
If your ignition system is old  . . replace wires, plugs, distributor cap,
rotor.

>While doing this the motor shakes the car pretty hard.
**** One or more cylinders not firing will cause this rough running of the
engine. The car will  "Buck" when driving and you step on the gas . . feels
like the ignition is cutting in and out. Thats the plug misfiring.

**** If problem was fuel related, engine would most likely die under load .
.not misfire.

**** Also, your fuel pump is under the car. The electrical wire contacts
corrode and loosen up. Remove fuel pump wires, clean and replace. Add a nut
to the terminal stud, if you have the crimp style contacts on the wires.

**** Google the problem . .use this syntax without the quotes "bucking
