Alright guys, I need some more help. When I start my car, my heat guage goes from cold, to over the hot side. I than tap my guage and it moves some more. Or I will be driving, and it will randomly switch from the middle to hot or vice versa. So what could the possibilities be? I am thinking that it might be the guages themselves. This has been happening since I got the car, but I am getting very sick of it. It makes me paranoid because my first motor overheated, and I am still paraoid about that. So what are some of the possibilities? Thanks.
