AAC Data Scan Reading

I have been looking at other peoples Data scan results, (my car is running rough) the only thing I can see that is different on my log is the AAC reading. My reading is very low at 12 the others I have looked at are much higher, will this cause my car to run rough?

    may not be a cause, but may be that theres a vacuum leak and the AAC is trying to 'gag in' to compensate for the extra air from the leak to try and control the idle. this may cause a lower reading. check all the vacuum hoses and the balance bar is down tight (an o-rings are sealing)

    may just be one bank thats leaking causing it to be rough.

     

    just my opinion. hope it helps
