Today while I was at lunch my CEL came on. My car runs good but the light is driving me crazy. I figured I would run by autozone and have them tell me what the code is so I can get this crap fixed. When I bought my car it had a SRI and I don't think it's installed correctly because it's missing the tube that goes over the intake. It also has a plug thing on the intake manifold that is leaking air. You can hear air hissing from the plug and it's louder than the sucking sound from my SRI. Could this be my problem?
