We have our first fillup since the pizza pan install. And unfortunately, it's a mulligan. Halfway through, the engine threw a couple codes (P0420 and P0172). And fuel economy dropped. The problem turned out to be a faulty MAF sensor. So I replaced it (with a Denso unit). Now everything is back to normal. But we need to "reboot" the pizza pan fuel economy test.
