For what it'* worth, here is a link to an article regarding testing for a vacuum leak with ether (starting fluid). I have done this many times and it works. If you have a leak you'll usually find it. I would also say that ether should be used sparingly and with caution. If you aren't comfortable with it don't do it. But it might be worth a try in the process of elimination.

Hmm, you might have a bad fuel injector. My dad'* had the same exact symptoms, turns out that one of his injectors went bad. Test your fuel pressure. I'm not exactly sure how you can test the injectors but however you do, give it a shot. I doubt that the MAF and/or the IAC, but at least check to make sure. Good luck.

Did you have the ICM tested or did you just swap it out as a test?

Well, Ive been noticing that the spark from the top two posts of the coil wasnt as hot as the other 4. I showed this to a couple buddies, we pulled the injector plugs, figured out that it was the top two posts, where the cylinders werent firing. On another mechanics recommendation, we swapped out the ICM. On another note autozone was 100 bucks cheaper than anywhere else for the module, only 125 bucks. Car now runs great, however today I now have to troubleshoot a slight transmission leak. It never ends. Does anyone think cauzing a big vaccum leak by pulling off the brake booster vaccum line could have damaged the ICM or was it just a freak of nature?

No bud that was a freak of nature.... The ICM usually does one of 2 things, either it fails completely, or it becomes very very unstable...lol... I have had that happen before... Its not pretty... Nothing you dod hurt the ICM in any manner..
You must have bought a Wells replacement module... Make totally sure you hang onto that reciept...
And the trans leak usually amounts to the pan gasket... I wish I had the factory original gaskets for my transmissions... Anymore I go down the road from autozone and get a filter kit with a rubber gasket as opposed to the cork gasket... I never leak a drop between tranny fluid changes...
Good Luck and let us know what you find with that leak..
