My wife's 2010 SRX with a 2.8 was throwing a over boost code every time you got into the throttle hard. After about 6 months it stop throwing the code and now I am getting a P0100 for the mass air flow sensor. I followed all of GMs pinpoint test can came up with nothing. So I replaced the mass air flow sensor with a new one I got from my local GM dealer. I am still having the problem so I load tested all the wires from it to the pcm and they are all good. Tried to take it to the dealer here in town and they told me they would not look at because the 2.8 is not a GM engine and the closest dealer that will is over 3 hours away. Any help would be grate.
