    I'm still having codes pop up on my 2010 GMC, I had a Volant intake, I figured it was the problem. I got rid of the intake, it fixed the problem for a little while, now the codes are back. Everyone is telling me it is an air leak at the Airraid TBS. I re-tightened the screws, sprayed some carb cleaner all around the intake connection areas, I did not hear the truck change it's idle. Could I have a bad MAF or O2 sensor?? .....Man I hate all the electronics on these newer trucks
