AT DRIVING SPEED ACCELERATION IS SMOOTH AND DECELERATION IS SMOOTH, BUT HOLDING NORMAL CRUISE IT ACTS LIKE IT'S MISSING. I HAVE CHANGED ROTOR, CAP, PLUGS AND WIRES.
IS THIS A SENSOR?

    Check for a stuck open EGR valve, very common on this engine, also pull any check engine codes and trace those ASAP.
