I own a 2007 Tahoe LTZ4WD and installed a clean air induction system along with a performance MAGGIE and throttle body spacer. Codes 171 & 174 came up. Had the intake and throttle body gaskets replaced. Dealer said that because I had these aftermarket items on that the engine light would continue to activate and turn off the stability and traction control system. It did. They told me to put it back to the stock intake and it would work properly. I did this and they're right. Wish they would have told me this before I spent all the money. Is there a trick to making this system work with the performance address?
