Dadej is most likely right. Usually when you have multiple gauges impacted it is a ground wire problem. Best quick fix (or test), is to find a common ground spot on the dash assembly and route a new wire from that point to a good chassis ground point - like in the run box in the outside compartment usually under the drivers seat. If that doesn't fix the problem, it's probably a hot power (+12Volt) problem. But a poor ground is many times the problem. Good Luck!
