1. I own a 2003 Nissan Sentra GXE and my heater is not working. Hot air blows out at first but for only a few seconds then it turns cold. I'm not sure what it might be.
2. Also. My engine temp keeps going up and back down to the middle where it normally is. It does this when I'm in traffic and when I'm going even going down the street at about 20 to 35 mph. I also noticed that today it also did the same thing when I was in the highway when I was going anywhere from 40 to 65 mph. I have already changed my thermastat and still the same thing.

When you have a misfire and combine that with over heating and coolant lose always make it 1st to check the head gasket
