No access to Tech 2, but I do have the open SID. I watched Mreq and Mair (=M calculated and Mair, I guess) and they are matched up almost exactly at idle, or when driving. I think my booster is leaky, but my guess is that the vacuum pump is pulling more vacuum than manifold so that the check valve closes to block the flow into manifold, not affecting measured air mass? I will try blocking the vacuum line hole at the manifold and see if I can reproduce high idle. If not, then I guess it is the booster?
