Anyone having speedometer problems? Mine craps out during road trips. It reads slower and slower speed eventually reading 0, but I'm still cruising around 70. After I shut down / fuel up, it goes back to normal. Can it be from the Diablo Preditor? I added it in December. It started acting funny just recently. (March) It's driving me nuts. Thanks for any input.

the speedo potentiometer is bad. You may be able to find someone who will replace it, or the whole instrument cluster has to be replaced.

Look up stepper motors on ebay if you want to fix it yourself, but you will need to recalbrate the speedo. Or look up speedometer repair service on ebay. I had mine fixed for $109 + shipping. He has quick service. I was only without it for a week, plus you can still drive the vehicle. The warranty is even better than chevy's...1 year unlimited mileage.
