My temperature gauge in the rally cluster is no longer working correctly. It will not go back to the low temp ("100" mark) when cold which I believe it is suppose to. It starts out at the middle mark and goes up an 1/8" so it does move, but not correctly. Also, every time when I turn the ignition on, the needle vibrates for ~5sec. before settling down. I changed the sensor to a correct Lectric Limited, and tried one other new one I had one and it still shows the same. The gauge itself I tested by unplugging the green wire from the sensor and it will not go to the low temp either. When I ground the green wire it will go up to the "hot" side. Actual temp on my car is 185F measured with digital infrared thermometer. Any thoughts?
