SURGING CRUISE CONTROL/SPEEDOMETER

2004 Kia Optima • 6 cylinder 2WD Automatic • 86,000 miles

My 2004 Kia Optima has problems with the speedometer and cruise control. The speedometer surges, jumps around and sometimes drops to 0 when the car is moving. The cruise control engages, but also feels like it surges and then disengages. Are the 2 problems connected and what is the fix?
