Lately I noticed that going over bumps and stuff make my gauges flicker and turn off and stuff some times... Even when i shift it does it too... but some times it wont do it for a long time... I have the 99 indiglo gauges btw... Good thing im getting a new cluster cause my rpm needle is about 800rpms too high man what a mess... wonder why they are flickering.??

 

maybe loose connections. Double check everything
