2000 Saturn SC2 running horrible!!

[into_despair]

I was looking for some help in diagnosing the problem with my car. I've already gone and put one of those autozone scanners on it, and it gave me a very vague idea of what could be wrong. It pulled a P0440 and P0507 code. I go to work and school full time so I don't have the time to be poking around at everyone of those possibilities, and I don't really have the money to take it to a mechanic atm either.

The check engine light came on a few months back, the acceleration has been bad since then, but it just recently started running worse. While accelerating the car jerks horribly, but then will smooth out if I give it more gas or let off a little bit. Does anyone have any suggestions that it could likely be? This is basically my last step before I end up having to take it to a mechanic, not sure how much more of this my car can take.

P0440 - EVAP system problem
P0507 - Idle RPM control High
Suspect bad plastic, rubber, gaskets, or seals.
1) Need to perform a smoke test on both the Intake + Evap system.

The two codes are related somehow. Whatever is causing the p0440 is probably causing the p0507 as well. Something in evap system is broken and probably causing a big vacuum leak. You'll need to remove the right front tire, IIRC, to access the charcoal canister. It is under the inner fender liner. Work your way back from there, checking all the lines for any breaks.
