strange idle problems...

[Nerfdude]

so, my car has some idling issues. for starters, when i start it (ha ha, pun!<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> it goes up to about 1100, then imediately plummets to about 200, then rises back up to around 1100. this morning, when i started it, it idled at 1400 RPM's.
after driving it a while, it dropped to about 700 or so, where it should be, but... what the hell was up with that?

check the archive and faq section. There's a couple topics of what it may be. Easiest would be to clean your AIV, so hopefully that's it.
