Please help. I am so frusterated with cars. I have a 99 dodge durango and the check gauge light keeps coming on and my oil gauge and other gauges will go to the top. After a while the gauge light goes off and the oil gauge and others go back to normal. This happens a lot when its cold outside and if I have my heart going it takes energy from that and my sterio shorts out when the check gauge light is on. What is going on? Now my car is starting to not want to start without some help sometimes.

please please please help....sugestions are needed
