It worked fine the other day but now all of a sudden it just starts pulsing and acting up and I'm not sure if it's accurate 

It could be a broken speedo cable. Worst case it’s the plastic gear in the gearbox stripping out. 

If the speedo cable isn’t it, the easiest fix is to use a GPS for speed readings.

try some wd40 inside the speedo cable its worked for me a few times 

on other vehicles ive pulled the cable out of the sleeve and cleaned and regreased it and they worked good after 

 

you might need to pull the cable from the trans side i cant remeber how the loyal spedo cable works
