NHTSA investigating 725k Ford, Mercury vehicles for stalling issue

Owners of Ford Escape, Mercury Mariner, Ford Fusion and Mercury Milan models, listen up. According to a report on Automotive News, the National Highway Traffic Safety Administration has opened an investigation into these four vehicles totaling an estimated 725,000 units. The investigation appears to center around a malfunctioning throttle body on non-hybrid models of the 2005-2012 Escape and 2011-2012 Fusion. With Mercury dying off after the 2011 model year, this probe will also apply to the 2005 through 2011 Mariner and the 2011 Milan. There has been some discussion around the Escape stalling issue for some time now, but this investigation appears to be larger in scope than before.
Though not a recall yet, NHTSA's Office of Defects Investigation (ODI) has received 123 complaints of stalling or surging vehicles, while Ford itself has logged 1,472 complaints. The investigation report, which is posted below, seems to indicate that a faulty circuit board for the throttle body could cause the vehicle to go into limp mode, which, according to NHTSA, could cause complaints of both stalling and surging.

Junkyard Gem: 1973 Mercury Montego MX Brougham Sawzall Convertible Edition

You know how it goes— the weather is warm, you want to do some top-down driving, and you lack a proper convertible... but you do have a hooptie Detroit car on one side of the garage and a big ol' Sawzall on the other. Put the two together and you have a Sawzall Convertible, which generally lasts for about one summer before it gets scrapped. Here's a fine example of such a car, photographed in a San Francisco Bay Area self-service junkyard. Most Sawzall Convertibles (yes, it should be called a roadster, but nobody does that) have raw, ragged metal edges, or maybe duct tape over the stumps of the amputated pillars, but someone went to the trouble to weld nice smooth metal covers over the hackage on this one. The windshield is gone. Instead, the windshield frame is ringed by tongue depressors held in place by gooey roofing tar. No, we don't know why. The Montego MX Brougham was a hot-selling personal luxury coupe in its day, selling for $3,041 in 1973. That's just under $17,000 in 2017 dollars. It must have been fun, cruising this thing on Bay Area streets with no roof and a rattle-can spray-bomb job. This one has the optional 400-cubic-inch V8 engine, rated at 171 horsepower.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.
