Hey all,
To start I replaced the cluster a while ago and that made it work, but after some spirited driving the needle dropped again. The hicas light also came on so I assumed it would be the speed sensor and replaced that, but it still doesn't work. It will occassionaly work after hitting a bump (it seems) but otherwise doesn't work. I've searched around but didnt see anything else suggested. What do you guys think? Any help is appreciated.

Thanks,
Corey
