Grand prix problems. It is cold af in Michigan The temp was about 7 and windchill at about - 17. I got in today after practice like usual and I went to turn out of school and it just died... It did thst about 5 times on the way home. It would die. I would put it in neutral it would start up. And then do not again once I gave it a substantial amount of gas it would die. It seems like if I gave it more than 50% throttle rpms would drop fast and die. then I turned into a side road close to my house to see if it was still doing it. I gave it some gas and it was ok... I noticed the engine temperature was going up so I figured it had something to do with it being cold. But I did just read on a page that it could be a crank sensor.
