when car is sitting still Running tach is fine and so is temp gauge. I start driving the temp gauge goes always to hot and stays. Tach stays normal most of time some time while driving it goes dead. Already checked the engine to body and the wiring harness grounds. Cleaned them and retightened all of them! Are there more that I should try? Got to get it working right so I can drive to Geos on the Gulf Friday. Cooling fan runs fine but these others just go crazy when I drive! Any body got any ideas what I should try next?

Instrument cluster uses the G202 ground, on the center instrument panel support. "Left of the cigar lighter on the center instrument panel support."

If it isn't that, I would suspect the pin/connector for the cluster. Is the fuel gauge and/or speedometer also acting up?
