Help diagnosing possible SAI problem.
I've been getting regular (about every 2 weeks or so) CEL for the SAI system P 0410 "signal implausible" as well as 1128 and 1130 which indicate the fuel trims are at full rich. The MAF is reading lowish, around 10-11 when it should be at 15. This leads me to believe that I am getting a vacuum leak somewhere in the SAI system.
Does that sound right and if there is a vavuum leak from the SAI, what are the usual suspects?
