temp guage problem

[Felix79]

My temp guage is no longer reading, it will move when I turn the ignition on to just under the White line under cold. I have pulled the display out and checked the nutt and cabels. What else could it be? Also the car is now very rough when cold.

If this is a M20, check out the plug/socket (and under the rubber boots) under the inlet manifold, where the injector loom connects to the engine loom

i had that problem and checked under the bonet and found that the dash board was fucked
