I've had my neon for a month and a half. When I got it, the driver air bag had been deployed but replaced, has aftermarket exaust, bigger than normal sized tires, auto. I noticed the temp gauge was a little higher than normal a couple times but goes back to normal shortly after I notice it. Today, while sitting in traffic, the temp gauge gets almost in the red zone. After i for on the highway the temp went back to normal. It is my daily driver and rims great until now. It has 185835 miles. I love this car and my wife and I need it to get to and from work and appointments. What could be the problem?
