this is indeed a common issue. But to me it sounds like your throttle position sensor is malfunctioning. it is approximately a $25 part at the local auto parts store.....just pay attention to the way the one on the car is pointing and install the new one exactly the same....if you install it pointing a different direction it will read incorrectly AND damage it.
