Hello all, I have a question for you I bought a 2002 Chevy 1500 5.3 LS, and the truck is awesome but the check engine light keeps coming on, after taking it to my mechanics and having them spend hours looking and test driving, he told me the Cold air intake is making the light come on, I've never heard of this so I tried cleaning the mass airflow sensors and I tried disconnecting the negative battery cable and doing a computer reset the light will go out for about 20 miles then it comes back so I just want to return to stock and be done with it my question in I bought a Air box but I cant seem to find the stock tubing that goes from the air box to the engine (I'm not sure of the name for it) any suggestions to where I could find it?

P.S would I need a new Mass air flow sensor?

Thanks
