Thanks for the Info..I'm about to install my s&b intake and this will come in handy if it comes up.When I installed my S&B I got a check engine light also. If Im not mistaken it was a P0606. If you turn the key on and off 3 times it will tell you the code. Once you have that write it down and then cycle the key on and off 5 times and it will clear it. Drive it and if you get the code back then look for the reason...Most likely the code will clear and you are good to go.
