Yes, I totally missed that one. There's a good example of using a vacuum gauge to your advantage, and a reminder that few of us have retained the skill to read one if we ever really had it. And for those of us with turbos, I know I should be watching the gauge when it isn't in boost, but I rarely give it a glance.

Anyhow, for another piece of "soft" data, here's the wife's 245 undergoing suction diagnostics for reference. The needle is fairly steady at 18, dropping about 1/2" whenever the oxygen sensor reports rich. The variations correspond to the sound I'm used to hearing from all these 4-bangers as the ECU makes mixture correction.
