Help, I installed a set of new "stock" gauges from Heartbeat City Camaro, in the center console of my 69 Camaro. It was the plug in unit with all 4 gauges, Temp, Battery, Fuel, and Oil. The temp gauge doesn't quite "peg" itself all the way on hot, but it moves into the orange, while idling, but then backs off as I drive it. It states the engine is overheating, but like I said, then backs off when being cooled as I drive. I know the engine is not overheating, never had this problem with the old gauges. Anyone got a solution to get this gauge to read correct?
