Just from changing the oil??

That seems kind of strange .....

I'd pull the ECU fuse and reset the ECU (about 2-3 minutes off), then start the car, and let it re-learn itself for two minutes. Turn the car back off, and start it again and drive to see if it does anyhting else.

Doesn't make sense that it would get all whacked just from changing the oil .....

You could've just knocked a wire loose while changing your oil. On the Si forum a member knocked the pin of the knock sensor off and severed it. He got a check engine light. He also knocked the emissions control wire loose. It can also be a vacuum line knocked off. Take a closer look. Good luck.

There's probably your problem. Find someone with a stock R ECU to try and swap it out to see if it helps.
