AC/idling weirdness
I know that when the AC compressor clutch thingie (that techincal enough for ya? 
) cycles on and off, the engine rpm's will go up and down. Mine's rather fast though.. off for two seconds, on for one second, off for two seconds, well.. you get the idea. Isn't it supposed to stay on and off for a greater amount of time than that? And if so.. What would be causing it to act like that?

Seems like I had an old Blazer a long time ago that did that when we overcharged the AC system. Have you put new refrigerant in it lately? Just an idea.
