Why winter sux..

EVERY year about this time (too cold to work outside) my car decides to get all wierd on me...
Last year the head cracked...
This year its a strange problem. Car idles fine but you give it gas and it dont go. No backfires or rough running.. it just dont go. Then all of a sudden its fine. Then bad again. Its too intermittant to trace very easily.

So I am rebuilding the battery pack on my laptop, building a cable, and gonna go hook it up to see whats going on..

Its so cold I cant even work under the hood long enough to test sensors.. grrr.. or should I say brrr!!
