I have a 2003 GMC Sierra Denali Quadrasteer with 116,000 miles. I have taken care of scheduled maintenance but have problems with the instrument gauges. The Tach is reading approx. 500rpm below normal, The 0il gauge is reading max and not reseting when the truck is turned off, Water and Trans temp. is reading low. The Speedometer and Voltage gauge seem to be working properly. I placed a test ground clip between the engine and battery(-). The test results were negative. Any information would be greatly appreciated.
Thank you,
