I have a 2000 tahoe with a 5.3. Wen I drive an hit a bump the gauge cluster needles jump an the warning lightd come on as if your jus started the truck. The olny 2 that don't mess up is oil pressure an battery vlotage. I've reoplaced the cluster 3 times an it does the same with each cluster. Had it in 2 shops and they couldn't figure it out. Any help is GREATLY appricated
