Running "hotter" spark plugs
right now its pretty cold in stl, down in the low teens, and my fc just dosnt want to start. i know running "hotter" plugs will help it start normally, but will they make a difference when it is this cold?

I don't think plugs do all that much for starting. I went to a hotter plug in my escort because the advanced timing was fouling out stock plugs but it had no affect on starting.

Hotter plugs prevent spark plug fouling. Colder plugs prevent detonation. www.howstuffworks.com has more information.
I wouldn't think spark plugs would affect starting. Hotter plugs will warm up faster but I can't see that making a difference. It's the spark that ignites. If your plug body ignites your fuel then you'll get detonation.

well, i dont have a camera, but they are black and have little spceks of **** on them and they reek of fuel. and some times they are moist.
well the last 2 times this has happened it has been the plugs. every time it wont start when it gets cold, i change the plugs and its ok. i have a very trustworty mechanic and family friend do the inspection the last 2 times and he agrees it has to be the plugs being too cold.
