This week, we proudly introduce a sure-fire cure for Car Talk-induced narcolepsy. Did we make the show more engaging and compelling? Sorry, we're not miracle workers. Meanwhile, in matters automotive, Mike is baffled by his Chevy's ability to suck a shirt in through its exhaust, and even more baffled by Tom and Ray's attempts to explain it. Also, Tamara's wondering if it's time to bid farewell to her beloved Vanagon for something a bit less barbaric; Marc wants to know if late night TV really can improve his gas mileage; and on Stump the Chumps, did Tom and Ray correctly diagnose Becka's cough and sputter? All this, plus a new Puzzler from the Fahrenheit-Celsius series, and lots more, this week on Car Talk.
