Decoding error code

I've finally traded up! I got rid of my 94 GXE and got a 98 SE 5-spd and couldnt be happier, except for the check engine light!

I entered the diagnostic mode and got 2 error codes, 0503 which I've been able to identify as a faulty O2 sensor in the rear cylider bank, and 0907.

I can not for the life of me find out what an 0907 error code means.

Does anyone know or can anyone tell me where i can find out without having to go to the dealer? I did try a site (http://vbxmaxima.8m.com/ecudecoder.html) but of course, there was an error on the page and it couldnt tell me squat!

Thanks for the help!

Please everyone, I'm desperate for an answer. I called the dealer trying to see if they'd give the info up without having to pay, no luck there!

If anyone knows anything about what the code is or where i can find an answer please let me know asap, I hate to have a "new" car and have something wrong with it the first week.



Thanks again for your help!
