I have replaced water pump, thermastat censor, thermastat, and EGR valve.
My car is not running hot but when I am driving the tempature gage light comes on then the car losses power. But car is cool and everything is circulating like it is suppose to. Do you know what this can be. THANKS

Felicia:

First, great name! My mother wanted me to be a Felicia, but that didn't happen. Lol My last name is spelled the same way with an ni at the end.

Regardless, it sounds like you have a bad temp sending unit. It isn't an expensive part and it's easy to replace. As far as the lack of power, that is normal if the computer thinks the engine is overheating. Try that. I feel it will help.

I don't know why, but this just showed up in my mail. Sorry it has been so long. Have you had any luck with the issue?
