    i would say you have a missfire one or more of the cylinders are missfireing when was the last tune up extra. One thing to remember is the person who changes these spark plugs may run into trouble with them breaking off in the cylinder heads very common problem in the ford V8 engines. Good luck and hope this helps. Is the engine light is flashing when u feel the jerking it also indicates a missfire condition.
