Cruise Control Sticks

Just recently fixed my cruise control (noticed the hook was off the throttle line) and glued it back on. Now every now and then when i get off the parkway, and come to a stop i notice the car running louder, and i need to put the brake really hard down to keep the car from jack rabbiting. When i turn the car off and on again, everything is fine and clears out.
Is this a normal problem with a quick fix, or a 1,000 investment. lol

Check that the PCM is getting an input from the brake switch.
