thanks for the feedback guys. the reason i waited so long to to get the CEL codes checked was because the earliest I could get the poor car into the dealership was a week after the light came on so it wasn't gonna do me any good to get the codes checked. I don't know, I'm having them replace the O2 sensors and then they'll start checking the other stuff, but they cant until the O2 sensors are replaced. That's gonna cost about 800 bucks for them to be replaced. I'm so happy that the maintenance on this car is so so expensive.
