Stock Gauges
 

How would I go about fixing the stock boost and temp gauge? I don't need them to be dead on enough to get aftermarket ones. I would settle for just having the stock ones work. The boost gauge moves only when I start it up and the temp gauge never moves. Any suggestions?

I have fixed alot of my gauge problems by taking the gauge cluster out, cleaning all the connections, and tightening the grounding screws...

What did you clean it with? Electrical parts cleaner? Is there anything I should look for while I have the cluster out. Are you talking about any specific grounding screws or all of them?
