Temperature gauge malfunction
The temperature gauge on my 2003 Corvette is malfunctioning. When the car starts the temp needle goes offscale right, returns to the actual block temperature and then returns to the far right (overheat) indication. The digital readout indicates XXX for temperature also and all other gauges are functioning properly, so there is no way to determine whether the car is actually overheating. This car has not been driven for the past two years, which should not be an issue.
