When I started it an idled it, it idiled fine, just at a lower RPM than normal... like it would go to where it usually idles at, then the RPM went down about 300 or 400.

Any pevious mechanical problems I've noticed was wiper delays not working, cruise control giving out, and squeaky front-right suspension... I don't know how those could make my car shake, sputter, and die :P.

You may want to check the voltages at the throttle position sensor. Check them at idle, wot, and make certain it goes up and down smoothly as the throttle is opened and closed. Do this without the engine running, with the key on. A bad TPS will also cause problems with the cruise control.

Because Ace of Spades isn't a mechanic, I'd recommend starting with the basics, and using a paper clip or jumper wire to check for error codes, as documented in the techinfo section, or having someone scan it for codes.
If any codes are stored, that'd be the starting point for troubleshooting. The SES light will also turn on without setting a code if the engine is simply idling at too low of an RPM value, but unless there are obvious problems such as a new puddle under the car or something smoking, I really think the first thing to do is to check for error codes.

Ok, here'* what the problem was...

One of the sensors on the intake was unplugged, and after some explaination, I found out that not having a computer that knows what to do can cause other problems, like the sypmtoms of a misfire or a clogged fuel filter. Plugged it back in, did another diagnositc, and took it for a drive... Worked beautifully.

Thanks for all your input, I appreciate it... and all you gurus out there that see a similar problem, ask them if any sensors are unplugged .
