I just bought a 2002 Z28 with 32k on it, I installed a texas speed lid on and and about 3 weeks later my service engine soon light is on and wont go off. i reset the computer and its still on. im 99% sure i installed the oxygen sensor correctly in the intake. any ideas? ( the lid is the only modification so far thats why i think its that)

I don't think it's the IAT sensor in the lid since the light didn't come on until 3 weeks later...and since it's still on after resetting the PCM you need to get the code pulled to see what's going on. Autozone will do it free.
