everytime im driving my speedometer will read the speed then all of a sudden it will start bouncing around from zero to 20 to 50 to 80 and back and forth. when im on the gas it wont jump it will climb up but when i let go it will bounce around.

My best guess is that something is interfering with our signal... Check your wiring

i had the same problem and it was theeth missin off my speedo gear, my speedo worked every now and then and it would bounce right before it would quit, i pulled the sensor to replace it and it was good just like 5 teeth were missing so it had a flat spot.
