Fans of spectacular car noises rejoice: this week's Car Talk features Dale from Lunenburg, Massachusetts, who's got a spot-on imitation of that blood-curdling whine coming from the engine of his Ford pick-up. But, are his foley skills enough to lead Tom and Ray to figure out what's causing that racket? Also, can two guys full of hot air explain global warming as a result of a simple Act of Congress? If it's Tom and Ray, that's a big, fat, "Sure, why not!" Global crisis averted, it's on to Heather and her GMC Jimmy purchased from Uncle Larry. Could that chugging, lugging and jerking be the result of a little, shall we say, "lack of diligence" on the part of Uncle Lar? In Charlotte, Patrick's hearing a loud "Brrrrrr!" Is it just the ABS doing its thing, or is disaster about to strike? Find out how ABS really works, its pros and con, and a little admonition about that shrink-wrapped owners manual. (Sorry, Pat.) Tom and Ray give some coaching in the great Anchorage MPG contest, a Honda dealer earns a piston-slap dope-slap, and, why is a Saab deciding that it'll only spend 35 dollars at the pump? All this, a new Puzzler, and a startling discovery on the way cars are handed off from one generation to the next in the Magliozzi household, this week on Car Talk.
