What is your question?
engine jerking,like a spark miss after engine warms up.when it starts this there is a loss of power.the rpm gauge will either jump up and down or go to o. when letting off of the gas the engine will keep running,but pressing on the gas it still chugs and jerks.

It could be so many things, its hard to say exactly what it is without being able to do some basic diagnostic test. Disconnect the EGR hose and plug the vacuum hose. Drive the car now and see if the hesitation is gone. The EGR distribution should be uniform to all four cylinders but the passage ways in the intake manifold get plugged and distribute all the EGR to one or two cylinders "leaning them out" and causing a missfire. Check your spark plugs and plug wires and don't forget to adjust the valves (they are mechanically adjusted and people forget to adjust them)
