My Delorean could possibly be overheating. I took it out today for a drive and the temperature gauge rose all the way to 260 degrees. the cooling fans cut on and off occanionaly. i let the car idle at 260 degrees for about 5 minutes and nothing happened. i then tapped the accelator and the temperature gauge went down to 220. Does this sound like the gauge is wrong? Or is more serious? Thanks Willie Vin 5043
