You most like have a bad crankshaft speed sensor, which is a very common failing part on your vehicle. It is located on the side of the engine facing the front of the vehicle (so the side closest to the radiator). It's on the engine block, about 3" above the oil pan and closer to the transmission side of the block. Its a circular black plastic sensor with a black protected wire coming from it.
First scan the vehicle, you'll most likely have a "engine speed sensor" fault. If you do, replace the sensor.
