Check engine light is on..

[Teknic]

I have recently bought my MSP. I has 24k miles on it. Everything is stock beside a Dual Boost Control, and Greedy Sp2 catback exhuast (no cat when i bought the car). There is a custom down pipe to the resanator. I had talk with the guy that i bought the car from and he says its the 02 sensor but he's not sure. Can any one give me a hand on this? (shrug) I'm a newbie so plz help.

get the code read.

either buy your own OBD2 reader, or go to your local autozone or kragen and have them read it for you.
