So, My odometer works fine but my speedometer jumps all over the place. I have put a new cluster in and a new cable in. Never did anything. My check engine light is not on. Any suggesting? It hasn't bothered me but I'm trying to get my Boost By Gears set up and speedo needs to work for the BBG to work. Thanks in advanced.

mine jumps to 100 when im going like 40 but only i really cold mornings

 

same here..mine is 10-15 miles faster then i am actually going. would like to know why

 

Lubricate the speedometer cable. My old Camry did this. I lubed it with that dry graphite stuff and it worked fine after that.

 

Yup, that's what I did for mine and it worked, even after getting a new speedo cable it still needed to be lubed.
