Wife's Celica GT-S is messing up.

[Broadwayblues]

My wife pulls in and I can hear her car from across the yard. 1990 Celica GT-S and it's sooo nice! But it's weeezing! She tells and shows me that it idles from 1-2 thousand up and down and I think that there is a vacuum leak somewhere in the hoses. The problem is that I can't tell where the leak could be. I don't see anything really wrong. The engine zooming is so loud that I can't hear where the leak could be.
Anyone have any ideas?

thanks!

if its a leak caused by a cracked hose, you're not really gonna be able to hear it. just check every single hose and connection. i know it sounds like a lot, but when u find the bad hose, you'll be so happy <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'>

Well it's been an interesting day.
I found the problem, an a/c idle up valve that has an adjutment screw on the bottom that fell out.
Interesting though I think that her Celica engine has more potential then my 92 240. It's front wheel drive though. If it was an all-trac my car would be stock and her's would be smoking...lol
