air conditioner shaking?

[stealth13]

When I'm driving or sitting and turn on the a/c the whole car starts to shake. Why would this be?

You got it. ISC is toast. Check dsmgraveyard.com, a local wrecker, the classifieds, etc.
How did you reset the idle?

i followed the guide that blackgst posted up there ^^
and i have a spare engine (except its a turbo '93 front wheel drive) but i think that part should be the same if I'm not mistaken. Next time i get a chance I'll try and swap them.

Mine seems to have fixed itself... Just driving with it on it eventually just learned to raise the rpm's.

Should be the same part. Just test it before you put it in.
