Faster when cold?? Shouldn't it be the other way around?

Hey all, how's it going?

I'm driving around a '89 fairmont, cfi and a 3 speed. Neway, basically I wanted to know why is it, that my car kicks arse when it's cold, but turns into, well, not a slug, but pretty close when it's warm?? I don't get this.

I'm not going to pretend to be an expert mechanic, but I know the basics, but I can't think of any reason why it would be faster, and more responsive when it's cold.

Any replies would be great.

Thanks guys..

One theory is that cold air has a greater density than hot (expanded) air, therefore has a similar effect to a bigger intake...

You shouldnt know its any quicker while cold anyway, 95% of engine wear occurs while the engine is cold.
